Gene Information

rabbit ... p16INK4a(1029)

General description

Cyclin-dependent kinase inhibitor 2A (CDK4I) or p16INK4a belongs to the Ink4 family of CDK inhibitors. The p16INK4agene is mapped to human chromosome 9p21. Structurally, p16INK4a comprises four ankyrin-type repeats (I–IV) .

Immunogen

The epitope recognized by PLA0178 maps to a region between residue 106 and 156 of human CDK4 inhibitor p16-INK4a using the numbering given in entry AAA92554.1 (GeneID 1029).

Biochem/physiol Actions

Cyclin-dependent kinase inhibitor 2A (CDK4I) or p16INK4a is a negative regulator of cyclin dependant kinase 4 (CDK4) and CDK6 kinase activity and cell cycle progression. The ankyrin repeats (I–IV) are crucial for their interaction with CDK4 and CDK6. P16INK4a regulates the cell cycle by inhibiting cyclin/CDK complex formation and the phosphorylation of the retinoblastoma protein (pRb). P16INK4a is a tumor suppressor and its mutations are associated with malignancies such as melanoma and astrocytoma and are the cause of Li-Fraumeni syndrome.

Physical form
