RPTP gamma, also known as Receptor-type tyrosine-protein phosphatase gamma, R-PTP-gamma or PTPRG is a protein tyrosine phosphatase (PTP) is a candidate tumor suppressor gene since it is located on human chromosome 3p14.2-p21, a region frequently deleted in certain types of renal and lung carcinomas. In situ hybridization analysis reveals that RPTP gamma mRNA is expressed in specific regions of the brain and that the localization of RPTP gamma changes during brain development. RPTP gamma is composed of a putative extracellular domain, a single transmembrane domain, and a cytoplasmic portion with two tandem catalytic tyrosine phosphatase domains. The extracellular domain contains a stretch of 266 amino acids with striking homology to the zinc-containing enzyme carbonic anhydrase (CAH), indicating that RPTP gamma and RPTP beta (HPTP zeta) represent a subfamily of receptor tyrosine phosphatases. RPTP gamma may have a function other than catalysis of hydration of metabolic CO2.
