Description

The arrival of any of the three stop codons (UAA, UAG and UGA) into the ribosomal A-site triggers the binding of a release factor (RF) to the ribosome and subsequent polypeptide chain release. In eukaryotes, the RF is composed of two proteins, eRF1 and eRF3. eRF1 is responsible for the hydrolysis of the peptidyl-tRNA, while eRF3 provides a GTP-dependent function. The ribosome releases the mRNA and dissociates into its two complex subunits, which can reassemble on another molecule to begin a new round of protein synthesis. It should be noted that at present, there is no factor identified in eukaryotes that would be the functional equivalent of the bacterial ribosome release (or recycling) factor, RRF, that catalyzes dissociation of the ribosome from the mRNA following release of the polypeptide View original pathway at:Reactome.

R-HSA-5691512 (Reactome) Protein acetylation, which can occur during or after polypeptide chain biosynthesis, helps protect the intracellular proteins from proteolysis. Acylamino-acid-releasing enzyme (APEH) is a cytosolic enzyme able to catalyse the preferential hydrolysis of terminal acetylated amino acids from small acetylated peptides. APEH prefers substrates with acetylated methionine, alanine and serine residues. Hydrolysis produces an acetylated amino acid and a N-terminus protein (Jones et al. 1991). APEH expression is reduced in renal cell carcinoma therefore may represent a tumor suppressor gene, whose loss contributes to the development of renal cell carcinoma (Erlandsson et al. 1991). The hydrolysis of an acetylated serine residue (NAc-Ser-protein) is shown here.
R-HSA-6800138 (Reactome) Class 1 release factors such as eukaryotic peptide chain release factor subunit 1 (ETF1) direct the termination of peptide translation in response to the termination codons UAA, UAG and UGA. ETF1 needs to be complexed with ERF3 in its GTP-bound form to be efficiently post-translationally methylated. HemK methyltransferase family member 2 (N6AMT1) is a heterodimeric methyltransferase that catalyses N5-methylation of ETF1 on glutamine 185 (Q185), using S-adenosyl L-methionine (AdoMet) as the methyl donor (Figaro et al. 2008). N6AMT1 forms a complex with multifunctional methyltransferase subunit TRM112-like protein (TRMT112)
