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.

It directly regulates the levels of two important phosphoinositide second messengers, PtdIns5P and phosphatidylinositol-(4,5)-bisphosphate (PtdIns(4,5)P2), one of the key metabolic crossroads in phosphoinositide signaling. It regulates the levels of nuclear PtdIns5P, which in turn modulates the acetylation of the tumour suppressor p53. It also interacts with and modulates nuclear localization of the high-activity PtdIns5P-4-kinase isoform PIP4Kalpha. Moreover, PIP5K2B is a molecular sensor that transduces changes in GTP into changes in the levels of the phosphoinositide PtdIns5P to modulate tumour cell growth.

It is possibly involved in a mechanism protecting against tardive dyskinesia-inducing neurotoxicity. PIP5K2A is associated with schizophrenia. It controls the function of KCNQ channels via phosphatidylinositol-4,5-bisphosphate (PIP2) synthesis, and plays a potential role in the regulation of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors.

Phosphatidylinositol phosphate kinase (PIPK) catalytic domain found in phosphatidylinositol 4-phosphate 5-kinase type-1 alpha (PIP5K1alpha) and similar proteins; PIP5K1alpha (EC 2.7.1.68), also termed PIP5K1A, or PtdIns(4)P-5-kinase 1 alpha, or 68 kDa type I phosphatidylinositol 4-phosphate 5-kinase alpha, or PIPKI-alpha, catalyzes the phosphorylation of phosphatidylinositol 4-phosphate (PtdIns4P) to form phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2). It mediates extracellular calcium-induced keratinocyte differentiation. Unlike other type I phosphatidylinositol-4-phosphate 5-kinase (PIPKI) isoforms, PIP5K1alpha regulates directed cell migration by modulating Rac1 plasma membrane targeting and activation. This function is independent of its catalytic activity, and requires physical interaction of PIP5K1alpha with the Rac1 polybasic domain. The family also includes testis-specific PIP5K1A and PSMD4-like protein, also known as PIP5K1A-PSMD4 or PIPSL. It has negligeable PIP5 kinase activity and binds to ubiquitinated proteins.

Phosphatidylinositol phosphate kinase (PIPK) catalytic domain found in 1-phosphatidylinositol-3-phosphate 5-kinase and similar proteins; 1-phosphatidylinositol-3-phosphate 5-kinase (EC 2.7.1.150) is also called FYVE finger-containing phosphoinositide kinase, PIKfyve, phosphatidylinositol 3-phosphate 5-kinase (PIP5K3), or phosphatidylinositol 3-phosphate 5-kinase type III (PIPkin-III or type III PIP kinase). It forms a complex with its regulators, the scaffolding protein Vac14 and the lipid phosphatase Fig4. The complex is responsible for synthesizing phosphatidylinositol 3,5-bisphosphate [PtdIns(3,5)P2] by catalyzing the phosphorylation of phosphatidylinositol 3-phosphate (PtdIns3P or PI3P) on the fifth hydroxyl of the myo-inositol ring. Then phosphatidylinositol-5-phosphate (PtdIns5P) is generated directly from PtdIns(3,5)P2. PtdIns(3,5)P2 and PtdIns5P regulate endosomal trafficking and responses to extracellular stimuli. PIKfyve is vital in early embryonic development. It forms a complex with ArPIKfyve (associated regulator of PIKfyve) and SAC3 at the endomembranes, playing a role in receptor tyrosine kinase (RTK) degradation. The phosphorylation of PIKfyve by AKT can facilitate epidermal growth factor receptor (EGFR) degradation. In addition, PIKfyve may participate in the regulation of the glutamate transporters EAAT2, EAAT3 and EAAT4, and the cystic fibrosis transmembrane conductance regulator (CFTR). It is also essential for systemic glucose homeostasis and insulin-regulated glucose uptake/GLUT4 translocation in skeletal muscle. It can be activated by protein kinase B (PKB/Akt) and further up-regulates human Ether-a-go-go-Related Gene (hERG) channels. This family also includes the yeast ortholog of human PIKfyve, Fab1. PIKfyve and its orthologs share a similar architecture. They contain an N-terminal FYVE domain, a middle region related to the CCT/TCP-1/Cpn60 chaperonins that are involved in productive folding of actin and tubulin, a second middle domain that contains a number of conserved cysteine residues (CCR) unique to this family, and a C-terminal catalytic lipid kinase domain related to PtdInsP kinases (or the PIPKc domain).
