功能: catalytic activity:A phosphoprotein + H(2)O = a protein + phosphate.,catalytic activity:Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate.,disease:Defects in CDKN3 are found in patients with hepatocellular carcinoma (HCC) [MIM:114550].,function:May play a role in cell cycle regulation. Dual specificity phosphatase active toward substrates containing either phosphotyrosine or phosphoserine residues. Dephosphorylates CDK2 at 'Thr-160' in a cyclin-dependent manner.,induction:Up-regulated in breast and prostate cancer cells.,similarity:Belongs to the protein-tyrosine phosphatase family.,subunit:Interacts with cyclin-dependent kinases such as CDC2, CDK2 and CDK3. Does not interact with CDK4. Interacts (via C-terminus) with phosphorylated CDK2 (via C-terminal helix). Interacts with MS4A3 (via C-terminus); the interaction enhances CDKN3 enzymatic activity.,
