General description
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.
~16 kDa observed. 16.53 kDa (isoform 1; p16INK4a), 11.22 kDa (isoform 2), and 17.88 (isoform 5; p16gamma) calculated. Uncharacterized bands may be observed in some lysate(s).
Immunogen
GST-tagged recombinant human p16INK4a internal fragment.
Application
Anti-INK4a (p16), clone 13H4.1 Antibody, Cat. No. MABE1451, is a highly specific mouse monoclonal antibody that targets INK4a (p16) and has been tested in Immunocytochemistry and Western Blotting.
Immunohistochemistry Analysis: A 1:50 dilution from a representative lot detected p16INK4a in human kidney and small intestine tissue sections.
