General description
1-phosphatidylinositol 3-phosphate 5-kinase (EC 2.7.1.150; UniProt Q9Y2I7; also known as Epididymis luminal protein 37, FYVE finger-containing phosphoinositide kinase, PIKfyve, Phosphatidylinositol 3-phosphate 5-kinase type III, PIPkin-III, Type III PIP kinase, Zinc finger FYVE domain containing 29) is encoded by the PIKFYVE (also known as CFD, FAB1, HEL37, KIAA0981, PIP5K, PIP5K3, ZFYVE29) gene (Gene ID 200576) in human. PIKfyve is a class III lipid kinase that is responsible for phosphorylating phosphatidylinositol (PtdIns) and phosphatidylinositol 3-phosphate (PtdIns3P) of their inositol ring at the D-5 position to form PtdIns3P and PtdIns(3,5)P2 (phosphatidylinositol 3,5-bisphosphate), respectively. PIKfyve forms a stable ternary heterooligomeric complex with its regulator ArPIKfyve (encoded by the VAC14 gene) and the Sac1 domain-containing PtdIns(3,5)P2 5-phosphatase Sac3 (encoded by the FIG4 gene), and both ArPIKfyve and Sac3 are required for maximal PIKfyve activity. PIKfyve is also known to interact with the Rab9 effector RABEPK and the kinesin adaptor JLP (encoded by SPAG9). By regulating endosomal trafficking, PIKfyve plays an important role in multiple biological processes, such as GLUT4 translocation, retroviral budding, autophagy, and neurodegeneration. Human PIKfyve is initially produced as a 2098-amino acid protein whose N-terminal initiator methionine is removed posttranslationally. PIKFYVE gene mutation is linked to corneal fleck dystrophy (CFD) characterized by white flecks scattered in all levels of the stroma.
