?cl28923: PIPKc Superfamily (this model, PSSM-Id:391950 is obsolete and has been replaced by 475131)
Phosphatidylinositol phosphate kinase (PIPK) catalytic domain family The Phosphatidylinositol phosphate kinase (PIPK) catalytic domain family includes phosphatidylinositol 5-phosphate 4-kinases (PIP5Ks) and similar proteins. PIP5Ks catalyze the phosphorylation of phosphatidylinositol phosphate on the fourth or fifth hydroxyl of the inositol ring, to form phosphatidylinositol bisphosphate. The family includes type I and II PIP5Ks (-alpha, -beta, and -gamma) kinases. Signalling by phosphorylated species of phosphatidylinositol regulates secretion, vesicular trafficking, membrane translocation, cell adhesion, chemotaxis, DNA synthesis, and cell cycling.
