PIK3CA - phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha Gene
Also Known as MCM; CCM4; CWS5; MCAP; PI3K; CLAPO; CLOVE; MCMTC; PI3K-alpha; p110-alpha
Species: Homo sapiens
About PIK3CA
This gene has 10 transcripts (splice variants), 275 orthologues, 9 paralogues and is associated with 271 phenotypes. Ubiquitous expression in fat (RPKM 10.3), gall bladder (RPKM 7.8) and 25 other tissues.
Summary
Phosphatidylinositol 3-kinase is composed of an 85 kDa regulatory subunit and a 110 kDa catalytic subunit. The protein encoded by this gene represents the catalytic subunit, which uses ATP to phosphorylate PtdIns, PtdIns4P and PtdIns(4,5)P2. This gene has been found to be oncogenic and has been implicated in cervical cancers. A pseudogene of this gene has been defined on chromosome 22. [provided by RefSeq, Apr 2016]
