PI4K2A (Phosphatidylinositol 4-Kinase Type 2 Alpha) is a Protein Coding gene. Diseases associated with PI4K2A include Ochronosis and Long Qt Syndrome 1. Among its related pathways are Metabolism and Inositol phosphate metabolism (KEGG). Phosphatidylinositolpolyphosphates (PtdInsPs) are centrally involved in many biologic processes, ranging from cell growth and organization of the actin cytoskeleton to endo- and exocytosis. PI4KII phosphorylates PtdIns at the D-4 position, an essential step in the biosynthesis of PtdInsPs.
