Abstract

A novel protein tyrosine phosphatase designated PTP-S31 and its subfamily are identified, as are nucleic acid molecule coding therefor. Included in this family are PTP-S31 proteins or glycoproteins having one, two, or three identified amino acid changes in previously defined consensus sequences in the catalytic phosphatase domains of known protein tyrosine phosphatases. The PTP-S31 proteins or glycoproteins may be produced by recombinant means. Antibodies to PTP-S31 proteins or glycoproteins and nucleic acid constructs coding therefor, and methods for screening molecules which can bind to PTP-S31 proteins or glycoproteins and inhibit or stimulate their enzymatic activity, are provided.
