Other Notes
Small volumes of anti-IRS-2 (pS731) antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

anti-IRS-2 (pS731) antibody
Insulin Receptor Substrate-2 (IRS-2), a 180kDa cytoplasmic docking protein, is one of the major endogenous substrates of the insulin receptor kinase. The insulin receptor mediates insulin action through the phosphorylation of substrate proteins. The major substrates of the insulin receptor kinase are the insulin receptor substrate (IRS) family of proteins, IRS 1, IRS 2, IRS 3, and IRS 4. IRS 2, a signaling molecule that mediates effects of insulin, Insulin-like growth factor 1 and other cytokines by acting as a molecular adaptor between diverse receptor kinases and downstream effectors. IRS proteins contain more than 70 potential Ser / Thr phosphorylation sites for kinases like PKA (cAMP-dependent protein kinase), PKC, and MAPK. The phosphorylation of Ser / Thr residues of IRS proteins has a dual function, serving either for a positive or negative modulation of insulin signal transduction.

NCBI Summary for IRS-2 (pS731)
This gene encodes the insulin receptor substrate 2, a cytoplasmic signaling molecule that mediates effects of insulin, insulin-like growth factor 1, and other cytokines by acting as a molecular adaptor between diverse receptor tyrosine kinases and downstream effectors. The product of this gene is phosphorylated by the insulin receptor tyrosine kinase upon receptor stimulation, as well as by an interleukin 4 receptor-associated kinase in response to IL4 treatment.
