Overview
PIK3R5 Regulatory subunit of the PI3K gamma complex. Heterodimer of a catalytic subunit (PIK3CG/p120) and a regulatory (PIK3R5a/p101) subunit. Interacts with G beta gamma proteins. Ubiquitously expressed with high expression in fetal brain compared to adult brain. Abundant expression is observed in cerebellum, cerebral cortex, cerebral meninges, and vermis cerebelli. Greatly activated by G gamma proteins. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
