Description

Predicted to have 1-phosphatidylinositol-3-kinase regulator activity. Predicted to be involved in insulin receptor signaling pathway; phosphatidylinositol phosphorylation; and regulation of phosphatidylinositol 3-kinase activity. Predicted to localize to phosphatidylinositol 3-kinase complex. Human ortholog(s) of this gene implicated in several diseases, including SHORT syndrome; astroblastoma; endometrial cancer (multiple); lung small cell carcinoma; and primary immunodeficiency disease (multiple). Is expressed in eye. Orthologous to human PIK3R1 (phosphoinositide-3-kinase regulatory subunit 1).
