Pik3r5 Gene Summary [Mouse]
Predicted to enable 1-phosphatidylinositol-3-kinase regulator activity and G-protein beta/gamma-subunit complex binding activity. Predicted to be involved in several processes, including phosphatidylinositol 3-kinase/protein kinase B signal transduction; phosphatidylinositol metabolic process; and positive regulation of intracellular signal transduction. Predicted to be located in centriolar satellite; cytosol; and membrane. Predicted to be part of phosphatidylinositol 3-kinase complex, class IA and phosphatidylinositol 3-kinase complex, class IB. 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). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Pik3r5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
