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.

Possible cell adhesion receptor. It possesses an intrinsic protein tyrosine phosphatase activity (PTPase) and dephosphorylates EPHA2 regulating its activity.; The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one.
