The protein tyrosine phosphatase family comprises transmembrane receptor-like and cytosolic forms. Although the exact biological functions of these enzymes are largely unknown, they are believed to counter-balance the effects of protein tyrosine kinases. We have previously identified and characterized a mammalian transmembrane protein tyrosine phosphatase, called LAR (leukocyte common antigen related gene), whose expression is often associated with proliferating epithelial cells or epithelial progenitor cells. This study investigates the potential role of LAR in the regulation of cell growth and death in mammals.
