This gene encodes a potent cyclin-dependent kinase inhibitor. The encoded protein binds to and inhibits the activity of cyclin-cyclin-dependent kinase2 or -cyclin-dependent kinase4 complexes, and thus functions as a regulator of cell cycle progression at G1. The expression of this gene is tightly controlled by the tumor suppressor protein p53, through which this protein mediates the p53-dependent cell cycle G1 phase arrest in response to a variety of stress stimuli. This protein can interact with proliferating cell nuclear antigen, a DNA polymerase accessory factor, and plays a regulatory role in S phase DNA replication and DNA damage repair. This protein was reported to be specifically cleaved by CASP3-like caspases, which thus leads to a dramatic activation of cyclin-dependent kinase2, and may be instrumental in the execution of apoptosis following caspase activation. Mice that lack this gene have the ability to regenerate damaged or missing tissue. Multiple alternatively spliced variants have been found for this gene.

A study in humans identified the CDKN1A as a radiation-inducible mRNA biomarker found increased in whole blood extract after total body radiation of cancer patients [Chen et al. DOI:10.1016/j.ijrobp.2005.10.014]. A study in human cadavers demonstrated that low myocardial expression of the CDKN1A transcript variant alt-a, referenced to GAPDH, is a characteristic molecular marker for distinguishing hypothermia deaths from those due to chronic ischemic heart disease and other cardiac/respiratory diseases, with significantly lower expression in hypothermia groups regardless of concomitant chronic ischemic heart disease [Kaija et al. DOI: 10.1097/MD.0000000000019399].
