Anti-Protein Tyrosine Phosphatase Receptor F (PTPRF) Antibody (56579-100ug)

PTPRF, like other members of the protein tyrosine phosphatase (PTP) family, is a signaling molecule that regulates a variety of cellular processes. PTPRF possesses an extracellular region, a single transmembrane region, and two tandem intracytoplasmic catalytic domains, and represents a receptor-type PTP. The extracellular region contains three Ig-like domains and nine non-Ig like domains similar to that of neural-cell adhesion molecule. PTPRF functions in the regulation of epithelial cell-cell contacts at adherents junctions as well as in the control of beta- catenin signaling. An increased expression level of PTPRF has been found in the insulin- responsive tissue of obese, insulin-resistant individuals and may contribute to the pathogenesis of insulin resistance. Two alternatively spliced transcript variants of this gene, which encode distinct proteins, have been reported.
