Protein Structure

UniProt Annotation

Function

Regulatory subunit of the PI3K gamma complex. Required for recruitment of the catalytic subunit to the plasma membrane via interaction with beta-gamma G protein dimers. Required for G protein-mediated activation of PIK3CG (By similarity). {ECO:0000250}.

Subcellular Localization

Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}. Membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.

Disease Associations

Ataxia-oculomotor apraxia 3 (AOA3) [MIM:615217]: An autosomal recessive disease characterized by cerebellar ataxia, oculomotor apraxia, areflexia and peripheral neuropathy. {ECO:0000269PubMed:22065524}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

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. {ECO:0000269PubMed:15797027, ECO:0000269PubMed:22065524}.
