Anti-IRS2 Antibody Picoband®

Insulin receptor substrate 2 (IRS2) is a protein that in humans is encoded by the IRS2 gene. It is mapped to 13q34. 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. IRS2 is expressed in many cells, it may be essential for signaling by several receptor systems.

Growth regulator. Inhibits the proliferation of a number of tumor cell lines. It regulates cytokine production, including IL-6, G-CSF and GM-CSF from endothelial cells (By similarity) . Uses only type II OSM receptor (heterodimers composed of OSMR and IL6ST) . Involved in the maturation of fetal hepatocytes, thereby promoting liver development and regeneration.
