The protein expressed by the gene CDKN2A acts as a negative regulator of normal cell proliferation by strongly interacting with CDK4 and CDK6. This interaction inhibits the ability of CDK4 and CDK6 to interact with cyclins D and to phosphorylate the retinoblastoma protein.

Western blot: Anti-CDKN2A antibody [EPR24167-43] (ab270058) staining at 1/2000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (Anti-GAPDH antibody [6C5] - Loading Control ab8245) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab270058 was shown to bind specifically to CDKN2A. A band was observed at 17 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in CDKN2A knockout cell line. To generate this image, wild-type and CDKN2A knockout HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.
