General annotation (Comments)

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 By similarity. UniProtKB Q16667

Catalytic activity

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. UniProtKB Q16667

A phosphoprotein + H2O = a protein + phosphate. UniProtKB Q16667

Subunit structure

Interacts with cyclin-dependent kinases such as CDK1, 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 By similarity. UniProtKB Q16667

Subcellular location

Cytoplasm › perinuclear region By similarity UniProtKB Q16667.

Sequence similarities

Belongs to the protein-tyrosine phosphatase family.
