Anti-INK4a (p16) Antibody, clone 13H4.1

32160702

Cyclin-dependent kinase inhibitor 2A (UniProt P42771; also known as CDK4I, Cyclin-dependent kinase 4 inhibitor A, Multiple tumor suppressor 1, MTS-1, p16-INK4, p16-INK4a, p16INK4A) is encoded by the CDKN2A (also known as CDKN2, MTS1) gene (Gene ID 1029) in human. The INK and CIP/KIP families of cyclin dependent kinase inhibitors (CDKis) protect cells from oncogenic signals-initiated cellular transformation. INK4a and INK4b (encoded by the CDKN2A and CDKN2B gene, respectively) constitute the INK4 subfamily of CDKis. INK4a and INK4b are induced by oncogenic Ras and are involved in cell cycle G1 arrest and cellular senescence. Inactivation of CDKN2A and CDKN2B are found in a wide variety of human malignancies and murine tumor models.

Clone 13H4.1 epitope lies within a region present in p16INK4a and the spliced isoforms 2 and 5 (UniProt P42771-1, P42771-2, and P42771-4 respectively), but absent from the spliced isoform 3 (p12; UniProt P42771-3), p14ARF/p19ARF or smARF (UniProt Q8N726-1 and Q8N726-2).

GST-tagged recombinant human p16INK4a internal fragment.
