A novel protein tyrosine phosphatase is the protein designated PTP 1D. The PTP 1D protein may be produced by recombinant means, for example using a nucleic acid construct encoding the protein as provided herein. Also disclosed is an antibody specific for an epitope of PTP 1D, protein. Methods for identifying compounds which bind to a PTP 1D protein and inhibit or stimulate its enzymatic activity, pharmaceutical compositions comprising PTP 1D, and methods for treating a disease associated with PTP 1D protein using such compositions, are provided. |
