Predicted to enable phosphatidylinositol 3-kinase catalytic subunit binding activity. Involved in negative regulation of phosphatidylinositol 3-kinase activity and negative regulation of phosphatidylinositol 3-kinase signaling. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. Is expressed in several structures, including brain meninges; genitourinary system; heart; lung; and oral epithelium. Orthologous to human PIK3IP1 (phosphoinositide-3-kinase interacting protein 1). [provided by Alliance of Genome Resources, Apr 2022]
