General description

ICA 512, also known as Receptor-type tyrosine-protein phosphatase-like N (R-PTP-N), or Islet cell antigen 512 (ICA 512) or Islet cell autoantigen 3, or PTPIA-2, or IA-2, and encoded by the gene PTPRN/ICA3/ICA512, is a required protein for endocrine and neuroendocrine secretory processes. ICA 512 may be involved in processes specific for neurosecretory granules, such as their biogenesis, trafficking and regulated exocytosis, or ICA 512 may have a more general role in neuroendocrine functions. ICA 512 interacts with phosphorylated syntrophin beta 2/Distrophin, protecting it from protein cleavage by calpain I. Dephosphorylation of Distrophin upon insulin stimulation disrupts the interaction and results in its cleavage. ICA 512 is a membrane protein and found within neuroendocrine secretory granules and endocrine tissues. ICA 512 is expressed in brain, pituitary and gut tissues including the pancreas. ICA 512 is also now used as a diabetes-specific islet autoantigen biomarker in type diabetes patients.

Target description

~65 kDa observed. The full length protein is cleaved to yield a 65 kDa mature protein form that contains a lumenal domain, and an intracellular cytoplasmic domain characterized by a juxtamembrane region (Piquer, S., et al. (2006). J Autoimmun. 26(3):215-222.).
