Gene of the day

PI4K2A Gene. Entrez GeneID of this gene is 55361. Its authoritative full name is phosphatidylinositol 4-kinase type 2 alpha. 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 (Barylko et al., 2001 [PubMed 11244087]).[supplied by OMIM]
