PI4KA - phosphatidylinositol 4-kinase alpha Gene
Also Known as SPG84; GIDID2; PIK4CA; PMGYCHA; pi4K230; PI4K-ALPHA
Species: Homo sapiens
About PI4KA
This gene has 18 transcripts (splice variants), 209 orthologues, 9 paralogues and is associated with 6 phenotypes. Ubiquitous expression in brain (RPKM 52.3), testis (RPKM 23.0) and 24 other tissues.
Summary
This gene encodes a phosphatidylinositol (PI) 4-kinase which catalyzes the first committed step in the biosynthesis of phosphatidylinositol 4,5-bisphosphate. The mammalian PI 4-kinases have been classified into two types, II and III, based on their molecular mass, and modulation by detergent and adenosine. The protein encoded by this gene is a type III enzyme that is not inhibited by adenosine. Alternative splicing results in multiple transcript variants encoding distinct isoforms.
