Gene Information

human ... CDKN2A(1029)

General description

Cyclin dependent kinase inhibitor 2A (CDKN2A), also known as P16-INK4A, belongs to the Ink4 (inhibitor of CDK4) family of CDK inhibitors. It is encoded by the gene mapped to human chromosome 9p21 within the INK4a/ alternate reading frame (ARF) locus. Human P16-INK4A is localized in both nucleus and cytoplasm, and its expression increases with ageing in skin and kidney tissues.


Peptide with sequence C-HARIDAAEGPSDIPD from the C Terminus of the protein sequence according to NP_000068.1.

Biochem/physiol Actions

Cyclin dependent kinase inhibitor 2A (CDKN2A), also known as P16-INK4A, arrests cell cycle progression by inhibiting S-phase and promotes apoptosis. The encoded protein has anti-proliferative biological activity, and is implicated in the retinoblastoma (Rb) protein pathway. P16-INK4A acts as a tumor suppressor and plays a vital role in ageing and cellular senescence. Increased expression of this protein might lead to various types of high grade cancers. P16-INK4A also facilitates cell invasion and angiogenesis. Bronchial lavage P16INK4A promoter methylation might function as a potential biomarker for diagnosis of lung cancer.
