PIK4CA (human)

Overview
PIK4CA Acts on phosphatidylinositol (PtdIns) in the first committed step in the production of the second messenger inositol- 1,4,5,-trisphosphate. Expressed ubiquitously. Highest levels in placenta and brain. Little or no expression in lung, liver, pancreas, testis or leukocytes. This is a type II PtdIns-4-kinase activated by detergents such as triton and inhibited by adenosine. Belongs to the PI3/PI4-kinase family. Type III PI4K subfamily. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
