PIK3C2A encodes the human gene, Phosphatidylinositol-4-phosphate 3-kinase catalytic subunit type 2 alpha. It may also be known as: Phosphatidylinositol 4-phosphate 3-kinase C2 domain-containing subunit alpha; PI3K-C2-alpha; PtdIns-3-kinase C2 subunit alpha; Phosphoinositide 3-kinase-C2-alpha; CPK; PI3-K-C2(ALPHA); PI3-K-C2A; phosphatidylinositol-4-phosphate 3-kinase, catalytic subunit type 2 alpha. The encoded protein is an enzyme with an amino acid length of 1686 and a mass of 190.7 kDa. PIK3C2A is a member of the PI3/PI4-kinase family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
