Preparation and Storage

Background: IA-2/PTPRN

IA-2 (insulinoma-assocated protein 2), also called PTPRN (protein tyrosine phosphatase-like N) and ICA512 (islet cell antigen 512), is a 130 kDa member of the receptor tyrosine phosphatase family of type I transmembrane enzymes. It is not active as a phosphatase but acts an autoantigen in type I (insulin-dependent) diabetes. It is mainly expressed in neuroendocrine cells types within pancreatic islets, adrenal medulla, pituitary, and the central nervous system, and is present within membranes of regulated secretory granules. It is induced by glucose and insulin in the pancreas and is thought to contribute to the growth of beta cells. Cleavage at a furin-like site at amino acid (aa) 448 creates a 60-66 kDa transmembrane fragment. Within the region used as an immunogen, human IA-2 shares 80% aa sequence identity with mouse and rat IA-2.
