Protein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. Enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis. May be involved in the progression of cardiac hypertrophy by inhibiting intracellular calcium mobilization in response to angiotensin II. Belongs to the protein-tyrosine phosphatase family. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
