Insulin receptor substrate 2

The IRS2 gene encodes a protein that is an important component of signal transduction. It constitutes the link between various receptor tyrosine kinases and downstream effectors. For instance, it acts downstream of insulin receptor, IGF receptor, and diverse cytokin receptors. Mutations in this gene are associated with insulin resistance and type 2 diabetes mellitus.
