Rabbit anti Human CDKN2A antibody recognizes human cyclin-dependent kinase inhibitor 2A (CDKN2A), a 16 kDa protein belonging to the CDKN2 cyclin dependent kinase inhibitor family.
CDKN2A acts as a negative regulator of cell proliferation by interacting strongly with CDK4 and CDK6, thus inhibiting their ability to interact with cyclin D and to phosphorylate the retinoblastoma protein.
CDKN2A is an important tumour suppressor and defects in its production results in tumour formation in a wide range of tissues, including cutaneous malignant melanoma and Li-Fraumeni syndrome.
