Netrins are secreted proteins that play a crucial role in neuronal migration and in axon guidance during the development of the nervous system. To date, several Netrins have been described in mouse and humans: Netrin-1, -3/NTL2, -4/h and G-Netrins. Netrin-1 is the most studied member of the family and has been shown to play a crucial role in neuronal navigation during nervous system development mainly through its interaction with its receptors DCC and UNC5. Members of the Deleted in colorectal cancer (DCC) family- which includes DCC and Neogenin in vertebrates- mediate netrin-induced axon attraction, whereas the C. elegans UNC5 receptor and its four vertebrate homologs Unc5a-Unc5d mediate repulsion.

R-HSA-373707 (Reactome) Netrin binding to DCC causes DCC clustering via its P3 domain in the cytoplasmic region and mediates attractive signaling.
R-HSA-373711 (Reactome) Netrin-1 promotes attraction of the commissural neurons to midline cells. It is secreted in the ventral midline (also known as the floor plate). The transmembrane DCC receptor is a Netrin-1 receptor, involved in the attractive effects of Netrin-1. Contact-dependent mechanisms promote extension of growth cones across the floor plate to the contralateral side, whereupon growth cones acquire sensitivity to the midline repellent Slit and grow away from the midline.
Netrin-1 binds directly to the fifth Fibronectin III motif of DCC, thereby inducing DCC clustering through the association between the DCC P3 domains, a process required for an attractive response.
R-HSA-373713 (Reactome) UNC-5 uses DCC as a co-receptor and binds to the DCC P1 domain with its DB domain to repel axons at low netrin concentration. It is generally thought that UNC5 receptor alone transduces short range signals whereas DCC-Unc5 complex transduces long range signals important for neuron migration, neurite growth and axon repulsion.
R-HSA-373715 (Reactome) DCC and ROBO1 heterodimerize via conserved sequence elements in their cytoplasmic domains, namely CC1 (conserved cytoplasmic region1) in ROBO1 and P3 in DCC. The formation of this complex is dependent on the previous interaction between ROBO and its ligand (SLIT). This physical interaction between ROBO:SLIT and DCC silences the attractive effect of Netrin:DCC and regulates the midline crossing of axons.
From the analysis of multiple double mutant combinations of the ROBO:SLIT and Netrin:DCC receptor-ligand pairs, it was deduced that ROBO repulsion on its own is sufficient to prevent commissural axons from re-crossing the midline, and that Netrin:DCC is not the only source of attraction at the midline (Stein and Tessier-Lavigne 2001, Garbe and Bashaw 2007).
R-HSA-373716 (Reactome) DCC interacts with the SH3/SH2 adaptor NCK1 in commissural neurons. This interaction is direct and requires the SH3 but not SH2 domains of NCK1. NCK1 can recruit Rac, Cdc42 and their effectors Pak and N-WASP to the activated receptor, thereby providing a direct link between DCC, Rho GTPases and numerous downstream signaling components that regulate the actin cytoskeleton.
R-HSA-373720 (Reactome) The carboxy (C) terminal domain of FADK1 interacts with the C-terminal P3 domain of DCC. This FADK1-DCC interaction is required for Netrin-1 to stimulate tyrosine phosphorylation and activation of FADK1.
R-HSA-373751 (Reactome) UNC-5 receptors interact with netrins and mediate the short-range repulsion signal. The extracellular Ig domains of Unc5 bind netrin.
R-HSA-374662 (Reactome) Ezrin is a member of the ezrin/radixin/moesin (ERM) family that acts as a linker between the plasma membrane and the actin cytoskeleton. Ezrin exists in a dormant, monomeric form in which its FERM/NERMAD and C-ERMAD domains are associated, masking membrane and F-actin binding regions. On production of PIP2, ezrin binds it, is recruited to the plasma membrane, and undergoes conformational changes unmasking the two binding sites.
R-HSA-374663 (Reactome) Phosphorylated Ezrin can link in microfilaments to the plasma membrane by direct association with transmembrane proteins such as the cytoplasmic domain of DCC.
R-HSA-374664 (Reactome) PIP2 places Ezrin at the membrane in a location to be phosphorylated, and thereby activated, by protein kinase-C theta.
R-HSA-374665 (Reactome) Siah-1 binds DCC and promotes its proteolysis via the ubiquitin-proteasome pathway. Siah-1 contains an N-terminal RING domain that is involved in proteolysis function and a C-terminal sequence that is involved in its oligomerization and binding to target proteins, such as DCC.
R-HSA-374667 (Reactome) Siah-2 binds to the DCC protein and promote its proteolysis via the ubiquitin-proteasome pathway.
R-HSA-374689 (Reactome) Netrin-1 is not only involved as an axon guidance cue during the development of nervous system but is also involved in the morphogenesis of the mammary glands. Netrin-1 acts as a short-range attractant and has an adhesive, rather than a guidance, function during mammary gland morphogenesis. In the developing mammary gland, netrin-1 acts locally through neogenin to maintain close apposition of cap cells and prelumenal cells at the leading edge of the TEB (Terminal end bud).
R-HSA-374692 (Reactome) Among netrin1 receptors neogenin is the only protein to interact with the repulsive guidance molecules (RGM). RGMs are membrane bound proteins involved in axon guidance in the visual system. Neogenin is the dependence receptor and cleaved by activated caspase-3 to trigger apoptotic cell death. RGM binding blocks the cleavage of neogenin so RGM functions as a cell survival factor.
R-HSA-374701 (Reactome) Netrin-1 stimulates phosphorylation of DCC on serine, threonine, and tyrosine residues. The experimental data suggest that tyrosine phosphorylation of DCC is a prerequisite step for DCC phosphorylation on serine and threonine residues. Fyn initiates the phosphorylation of the tyrosine residue 1420 in the DCC cytoplasmic domain. This phosphorylation of DCC in turn facilitates the DCC-Fyn interaction, forming a positive reinforcement cycle.
R-HSA-376122 (Reactome) DSCAM and DSCAML1 proteins are involved in homophilic intercellular interactions and these recognition events may play a role in neural connectivity. Recent studies in mouse demonstrate that DSCAM is selectively expressed in subclasses of cells and suggest that it uses homophilic repulsion to simultaneously promote both self avoidance (an essential developmental mechanism that allows axonal and dendrite processes to uniformly cover their synaptic fields) and tiling (ensures that the receptive fields of neurons from the same class do not overlap with one another) (Fuerst et al. 2008).
R-HSA-376123 (Reactome) DSCAM directly binds to serine/threonine-protein kinase PAK1 and this interaction is enhanced by the presence of Rac1 protein. Rac1 interacts with the CRIB motif in the N-terminal domain of PAK1 and DSCAM interacts with the kinase domain of PAK1. Rac1-bound PAK1, which is already active, has higher affinity for DSCAM, which may further regulate PAK1 activation.
R-HSA-376126 (Reactome) DSCAM binds netrin-1 and directs the turning of axons towards netrin-1 source independent of DCC or cooperatively depending on the cellular and developmental context. Signaling mechanisms activated by netrin-1 downstream of DSCAM involve phosphorylation of Fyn and PAK1.
R-HSA-418850 (Reactome) RhoGEF complexed with Netrin-1-DCC induces guanine nucleotide exchange by Cdc42, activating it. Activated Cdc42 activates N-WASP, which promotes the nucleation of F-actin via the Arp2/3 complex. Netrin-1, via DCC, influences cellular motility by regulating actin-based membrane extension through the activation of Cdc42.
R-HSA-418856 (Reactome) Rho GEF's DOCK180 and Trio directly associate with DCC, activate Rac-1 on DCC stimulation and cause cell spreading.
R-HSA-418858 (Reactome) When Netrin-1 binds to the DCC-NCK1 complex, a conformational change in NCK1 promotes interaction between the SH2 domain proteins, leading to recruitment and activation of RhoGEFs DOCK180 and Trio. These GEFs mediate Netrin-1 signaling in axon outgrowth and guidance through their ability to activate Rac1 and Cdc42.
R-HSA-418859 (Reactome) Multiple sites on UNC5C are phosphorylated after NTN1 (netrin-1) stimulation. An activated SRC tyrosine kinase induces phosphorylation of UNC5C at multiple cytoplasmic tyrosine residues including highly-conserved residues 449, 454, 568, 649 and 667. Phosphorylation of these residues creates potential binding sites for cytoplasmic signaling proteins.
R-HSA-418863 (Reactome) PTPN11 (SHP2) is recruited to the phosphorylated UNC5C receptor after netrin-1 (NTN1) stimulation, in a fashion that requires binding of the PTPN11 SH2 domains to the Tyr568 (Y568) phosphorylated motif. The functional significance of the UNC5C- PTPN11 interaction has not been reported. PTPN11 might negatively regulate tyrosine phosphorylation of UNC5C receptor, facilitating resensitization of the receptor to the netrin-1 signal.
R-HSA-418865 (Reactome) Unc-115/AbLIM is a key regulator of lamellipodia and filopodia in the growth cone during axon pathfinding and acts downstream of Rac GTPase signaling. It acts as a scaffold to recruit other actin-modulating complexes involved in lamellipodia and filopodia. Unc-115/AbLIM is locally recruited to the plasma membrane by activated Rac1 and subsequently dephosphorylated on serine 617. Dephosphorylated Unc-115/AbLIM then might interact with other molecules at the plasma membrane to induce formation of lamellipodia and filopodia by reorganization of the actin cytoskeleton.
R-HSA-418866 (Reactome) DCC interacts directly with PITPalpha and this interaction is enhanced in the presence of Netrin-1. The interaction of DCC with PITPalpha requires the carboxy-terminal dmain of both the proteins. PITPalpha signaling pathway is important for netrin-1 mediated axon outgrowth. Netrin-1 activates PITPalpha to regulate local phosphoinositide (PI) synthesis, which is important for PI3K dependent neurite elongation.
R-HSA-418868 (Reactome) Activated (phosphorylated) FADK1 acts as a scaffold and recruits src tyrosine kinases Src and Fyn to DCC. These tyrosine kinases phosphorylate DCC which is critical for Netrin-1 signaling.
R-HSA-418872 (Reactome) FADK1 interacts with the C-terminal P3 domain of DCC complexed with Netrin-1, and undergoes tyrosine phosphorylation and activation. Netrin-1-DCC binding thus leads to the autophosphorylation of tyrosine 393 in FADK1.
R-HSA-418874 (Reactome) The adaptor protein Nck-1 binds to DCC and recruits Rac-1, Cdc42 and their effectors PAK-1 and N-WASP to the activated receptor. Both Cdc42 and Nck-1 are activators of N-WASP. Cdc42 in its active GTP bound form binds to the CRIB domain of N-WASP and this interaction along with PIP2 results in the activation of N-WASP. Nck-1 activate N-WASP via binding of its SH3 domain to the proline rich domain of N-WASP. Nck-1 also possess an SH2 domain that associates directly with activated tyrosine kinase receptors which can phosphorylate N-WASP.
R-HSA-451345 (Reactome) DSCAM and DCC (Deleted in Colorectal Carcinoma) form a receptor complex in commissural axons in the absence of netrin1. They associate through a transmembrane interaction. The functional implication of this interaction is not known, but may allow DCC and DSCAM to contribute to other guidance pathways in a netrin1 independent fashion. It may serve as a way to hold DSCAM and DCC in a resting state, until netrin1 reaches a critical concentration at which both receptors are activated.
R-HSA-451347 (Reactome) DSCAM can stimulate the activation of JNK, one of the downstream events induced by activated PAK1. From the experiment using various dominant negative mutants it was suggested that PAK1 and MKK4 play a role in JNK activation.
R-HSA-451366 (Reactome) Its also observed that DSCAM can activate p38 MAP kinase along with JNK. Human DSCAM likely activates PAK1, JNK and p38 MAP kinase and these intracellular signaling events are similar to those activated by Drosophila Dscam. This suggests that the human DSCAM molecule may have physiological functions similar to Drosophila Dscam in axon guidance.
R-HSA-593672 (Reactome) Myosin-X, an unconventional myosin implicated in cell adhesion and filopodia elongation interacts with DCC and Neogenin and helps in their distribution in neurites. Myosin-X functions to transfer cargo proteins into filopodia and its hypothesized that Myosin-X may deliver DCC to filopodia on Netrin-1 stimulation.
R-HSA-593685 (Reactome) DCC and UNC5A, are also receptors for Netrin-4. The LNT domain of Netrin-4 is the key domain for this specific binding. Netrin-4 might also mediate attractive action through DCC and repulsive action through UNC5A.
R-HSA-593690 (Reactome) Netrin-1-DCC mediated signaling rapidly phosphorylates PLCgamma. Netrin-1 mediated PLC activation depends on recruitment of PITPalpha to DCC. Stimulation of PLC signaling and hydrolysis of PIP2 by netrin-1 in neurons is time-dependent, with a maximal activity observed within 15 min of netrin-1 stimulation.
R-HSA-622357 (Reactome) PIKE-L a brain-specific GTPase selectively associates with UNC5B but not with other family members of UNC5. Netrin-1 enhances this interaction and this interaction triggers the activation of PI3K kinase signalling, prevents UNC5B's pro-apoptotic activity and enhances neuronal survival.
R-HSA-622382 (Reactome) PIP2 hydrolysis appers to be an important mechanism for netrin-1 mediated neurite elongation. Netrin-1 alone could not elicit hydrolysis of PIP2 but depends on the stimulation of DCC and PLCgamma.
R-HSA-622390 (Reactome) Netrin-1, through its activation of DCC, triggers TRPC channel mediating the Ca+2 influx that is required for the growth cone turning. The effect of netrin-1 on TRP currents in the neurons is studied in Xenopus. In cultured Xenopus spinal neurons, Netrin-1 evoked Ca+2 influx and a depolarizing, TRPC-like current in both soma and growth cones. Inhibition of the Xenopus homologue of mammalian TRPC1 (XTRPC1) prevented Ca+2 influx, TRPC-like current activation and the chemotropic turning of the growth cone in response to a gradient of Netrin-1.
Netrin-1 receptor signalling to TRPC channels is mediated via hydrolysis of PIP2 by PLCgamma which then activates TRPC channel activity through IP3 and DAG.
