Phosphatidylinositols are a family of lipids under the phosphatidylglyceride class. This pathway specifies several metabolic conversions between PIP, PIP2, PIP3 and other metabolites. Phosphorylation sites on the individual metabolites are drawn as states, with the location added as a number. The main interactions within this pathway are based on Figure 1 of Rusten et al, annotated with biochemical interaction database Rhea, and diseases (depicted in pink) with corresponding OMIM-identifiers.. Dashed lines depict proposed interactions which have not been characterised (yet)

PtdIns(5)PPtdIns(4,5)P2mim-conversion12281 (Rhea) The addition of a third phosphate to obtain PtdIns(4,5)P2 can be performed by two enzymes, which either add the phosphate at the D4 or D5 position in the inositol ring. This last phosphorylation step is depending on where the second phosphphate is located (D5 or D4 repectively). Rephrased from [PMID: 9367159]: "The type I enzyme PIP-4-kinase phosphorylates PtdIns-4-P at the D-5 position (of the inositol ring).The type II enzyme however ( abundant in some tissues), phosphorylates PtdIns-5-P at the D-4 position, and thus should be considered as a 4-OH kinase, or PIP(4)K."
