Insulin receptor substrate 1 is a signalling adapter protein that in humans is encoded by the IRS1 gene. It is mapped to 2q36.3. This gene exhibited no intrinsic enzyme activity, and it can serve as a docking protein involved in binding and activating other signal transduction molecules after being phosphorylated on tyrosine by insulin receptor kinase. IRS1 plays a key role in transmitting signals from the insulin and insulin-like growth factor-1(IGF-1) receptors to intracellular pathways PI3K/Akt and Erk MAP kinase pathways. IRS1 also has important biological function for both metabolic and mitogenic(growth promoting) pathways. In addition to those, it is a key regulator of PI3K within malignant cells.
Titration of the IRS1 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
Human partial recombinant protein (AA 1041-1242) was used as the immunogen for this IRS1 antibody.
The lyophilized IRS1 antibody can be stored at 4oC to -20oC. After reconstitution, aliquot and store at -20oC. Avoid repeated freeze/thaws.
