pubmed:abstractText
DNA sequences encoding a novel member of the receptor protein tyrosine phosphatase (R-PTP) family, termed PCP-2, were identified in a human pancreatic adenocarcinoma cDNA library. Human PCP-2 cDNA predicts a protein of 1430 amino acids with a calculated Mr of 160 kDa. The predicted PCP-2 enzyme consists of a 740 amino acid extracellular region, a single transmembrane domain, and a 666 amino acid intracellular portion. The extracellular sequence contains a MAM (meprin/A5/PTPmu) domain, an immunoglobulin-like domain and four fibronectin type III-like repeats, suggesting that it is a member of the PTPkappa and PTPmu subfamily. The intracellular region contains two tandemly-repeated protein tyrosine phosphatase domains. Northern blot analyses revealed a single transcript of 5.5 kilobases, which is expressed at different levels in many human tissues except spleen and placenta. Upon transfection of PCP-2 cDNA into human embryonic kidney fibroblast 293 cells, a protein with an apparent Mr of 180 000 was detected by immunoblot analysis. This size was reduced to the predicted Mr upon treatment with endoglycosidase F, indicating that PCP-2 is glycosylated and, hence, expressed at the cell surface. A potential role of PCP-2 in cell-cell recognition and adhesion is supported by its co-localization with cell adhesion molecules, such as catenin and E-cadherin, at sites of cell-cell contact.
