The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2). Catalyzes the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 3,5-bisphosphate. Required for endocytic-vacuolar pathway and nuclear migration. Plays a role in the biogenesis of endosome carrier vesicles (ECV)/ multivesicular bodies (MVB) transport intermediates from early endosomes.

Required for endocytic-vacuolar pathway and nuclear migration. The product of the reaction it catalyzes functions as an important regulator of vacuole homeostasis perhaps by controlling membrane flux to and/or from the vacuole.

Catalyzes the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 3,5-bisphosphate. Required for endocytic-vacuolar pathway and nuclear migration. Has a role at a late stage in endosome-related membrane trafficking, at a point when signal termination has occurred. Is not required for receptor silencing.

Catalyzes the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 3,5-bisphosphate. Required for endocytic-vacuolar pathway and nuclear migration. The product of the reaction it catalyzes functions as an important regulator of vacuole homeostasis perhaps by controlling membrane flux to and/or from the vacuole. Hyperosmotic shock-induced increase in the levels of PtdIns(3,5)P2 requires the presence of VAC7, VAC14, and/or FIG4.

The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2) (By similarity). Catalyzes the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 3,5-bisphosphate. Required for endocytic-vacuolar pathway and nuclear migration. The product of the reaction it catalyzes functions as an important regulator of vacuole homeostasis perhaps by controlling membrane flux to and/or from the vacuole (By similarity). Required for survival under conditions of nitrogen starvation. May have a role in the secretion of pheromone peptides.

CD alignment includes type II phosphatidylinositol phosphate kinases (PIPKII-beta), type I andII PIPK (-alpha, -beta, and -gamma) kinases and related yeast Fab1p and Mss4p kinases. Signaling by phosphorylated species of phosphatidylinositol regulates secretion, vesicular trafficking, membrane translocation, cell adhesion, chemotaxis, DNA synthesis, and cell cycling. The catalytic core domains of PIPKs are structurally similar to PI3K, PI4K, and cAMP-dependent protein kinases (PKA), the dimerization region is a unique feature of the PIPKs. Length = 313
This family contains a region from the common kinase core found in the type I phosphatidylinositol-4-phosphate 5-kinase (PIP5K) family as described in. The family consists of various type I, II and III PIP5K enzymes. PIP5K catalyzes the formation of phosphoinositol-4,5-bisphosphate via the phosphorylation of phosphatidylinositol-4-phosphate a precursor in the phosphinositide signaling pathway. Length = 255
