Gene:
phosphatidylinositol-3-phosphate/phosphatidylinositol 5-kinase, type III
Description:
Supports the intracellular PIP pool and to a lesser extent, the PI 4,5-P(2) pool. It generates PIP from PI and, to a lesser extent, PI 4,5-P(2) from PI 4-P. There are indications that it phosphorylates the D-5 rather than the D-4 position. Has a role in endosome-related membrane trafficking (By similarity).
