Pik3r5 - phosphoinositide-3-kinase regulatory subunit 5

Predicted to enable 1-phosphatidylinositol-3-kinase regulator activity. Predicted to be involved in G protein-coupled receptor signaling pathway; positive regulation of MAP kinase activity; and regulation of phosphatidylinositol 3-kinase activity. Predicted to be located in centriolar satellite and cytosol. Predicted to be part of phosphatidylinositol 3-kinase complex. Is expressed in brain and retina nuclear layer. Human ortholog(s) of this gene implicated in ataxia with oculomotor apraxia type 3 and colon cancer. Orthologous to human PIK3R5 (phosphoinositide-3-kinase regulatory subunit 5).
