Summary: Enables several functions, including 14-3-3 protein binding activity; insulin receptor binding activity; and phosphatidylinositol 3-kinase binding activity. Involved in cellular response to glucose stimulus; cellular response to peptide; and insulin receptor signaling pathway. Predicted to be active in cytosol and plasma membrane. Biomarker of metabolic dysfunction-associated steatotic liver disease and osteoporosis. Human ortholog(s) of this gene implicated in type 2 diabetes mellitus. Orthologous to human IRS2 (insulin receptor substrate 2). [provided by Alliance of Genome Resources, Dec 2024]

Chronic periapical lesions are associated with decreased insulin signaling - evaluated according to insulin receptor substrate (pp185-insulin receptor substrate 1 [IRS-1]/insulin receptor substrate 2 [IRS-2]) tyrosine phosphorylation status, IRS-1 serine phosphorylation status, and IRS-1 and IRS-2 content - in the skeletal muscle of rats

IRS-2 was one of the targets of miR-126. MiR-126 inhibited the beta-cell proliferation through IRS-2 instead of IRS-1. MiR-126 may take part in the glucose homeostasis both through its target IRS-2 and IRS-1.

reduced insulin secretion during protein restriction directly increased hepatic IRS-2 as a rapid response on day 1, while additional mechanisms contributed to the upregulation of IRS-2 on day 7
Title: Insulin injection restored increased insulin receptor substrate (IRS)-2 protein during short-term protein restriction but did not affect reduced insulin-like growth factor (IGF)-I mRNA or increased triglyceride accumulation in the liver of rats.
Data suggest P38/Mapk14 (mitogen activated protein kinase 14) is involved in glucolipotoxicity-induced apoptosis in pancreatic beta-cells via phosphorylation of Irs2; thus, P38/Irs2 play roles in beta-cell response to hyperglycemia/hyperlipidemia.

The study identified the serine phosphorylation (p-Ser) sites induced by PKC-Beta activation or AngII, which inhibits insulin-induced p-Tyr sites on IRS2 and its signals in endothelial cells.

Data suggest that down-regulation of insulin signaling pathway (Irs1, Irs2, and insulin-like growth factor-1) in type II diabetic osteoporosis model occurs either sooner or more dramatically in bone as compared to liver, kidney or skeletal muscle.

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.
