CDKN1A holds a key part in the cellular response to DNA mutation. CDKN1A overexpression causes cell cycle to stop. When collaborating with CDK2 complexes, CDKN1A aids to prevent kinase activity and inhibits progression through G1/S. Nevertheless, CDKN1A can additionally increase assembly and activity in complexes of CDK4 or CDK6 and cyclin D. CDKN1A is a vital intermediary by which p53/TP53 facilitates its part as an inhibitor of cellular proliferation as a reaction to DNA impairment.
CDKN1A Human Recombinant produced in E. coli is a single polypeptide chain containing 184 amino acids (1-164) and having a molecular mass of 20.2 kDa.CDKN1A is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
| UniProt Protein Function: | p21Cip1: a cell-cycle regulatory protein that Interacts with cyclin-CDK2 and -CDK4, inhibiting cell cycle progression at G1. Its expression is tightly controlled by p53, through which this protein mediates the p53-dependent cell cycle arrest at G1 phase. |

| NCBI Summary: | 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. [provided by RefSeq, Sep 2015] |
