Summary: Enables several functions, including insulin receptor substrate binding activity; kinase regulator activity; and phosphatidylinositol 3-kinase regulatory subunit binding activity. Involved in several processes, including cell surface receptor protein tyrosine kinase signaling pathway; negative regulation of stress fiber assembly; and positive regulation of cellular component organization. Acts upstream of or within several processes, including apoptotic signaling pathway; negative regulation of osteoclast differentiation; and positive regulation of tumor necrosis factor production. Located in several cellular components, including cell-cell junction; cis-Golgi network; and perinuclear endoplasmic reticulum membrane. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and integumental system. Used to study SHORT syndrome and X-linked agammaglobulinemia. Human ortholog(s) of this gene implicated in several diseases, including SHORT syndrome; agammaglobulinemia 7; astroblastoma; endometrial cancer (multiple); and immunodeficiency 36. Orthologous to human PIK3R1 (phosphoinositide-3-kinase regulatory subunit 1). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
