Also known as KAPCDI1
Summary
CDKN3 (cyclin dependent kinase inhibitor 3, HGNC:1791) is a protein-coding gene on chromosome 14q22.2, encoding Cyclin-dependent kinase inhibitor 3 (Q16667). May play a role in cell cycle regulation.
The protein encoded by this gene belongs to the dual specificity protein phosphatase family. It was identified as a cyclin-dependent kinase inhibitor, and has been shown to interact with, and dephosphorylate CDK2 kinase, thus prevent the activation of CDK2 kinase. This gene was reported to be deleted, mutated, or overexpressed in several kinds of cancers. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Function. May play a role in cell cycle regulation. Dual specificity CC phosphatase active toward substrates containing either phosphotyrosine or phosphoserine residues. Dephosphorylates CDK2 at ‘Thr-160’ in a cyclin-dependent manner.
Subunit / interactions. 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.
Subcellular location. Cytoplasm. Perinuclear region.
Disease relevance. Hepatocellular carcinoma (HCC) [MIM:114550] A primary malignant neoplasm of epithelial liver cells. The major risk factors for HCC are chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, prolonged dietary aflatoxin exposure, alcoholic cirrhosis, and cirrhosis due to other causes. The gene represented in this entry may be involved in disease pathogenesis.
Induction. Up-regulated in breast and prostate cancer cells.
Similarity. Belongs to the protein-tyrosine phosphatase family.
