CDK2 Protein, Human (His)

CDK2 is an important serine/threonine protein kinase that plays a critical regulatory role in the cell cycle, especially during meiosis. It phosphorylates various substrates (CTNNB1, USP37, p53/TP53, NPM1, CDK7, RB1, BRCA2, MYC, NPAT, EZH2) and coordinates centrosome duplication and initiation of DNA synthesis at the G1-S transition. CDK2 Protein, Human (His) is the recombinant human-derived CDK2 protein, expressed by E. coli , with N-6*His labeled tag.

CDK2, a serine/threonine-protein kinase, intricately regulates the cell cycle, playing an indispensable role in meiosis while being dispensable for mitosis. Operating at the nexus of cellular processes, CDK2 phosphorylates a diverse array of substrates, including CTNNB1, USP37, p53/TP53, NPM1, CDK7, RB1, BRCA2, MYC, NPAT, and EZH2. It orchestrates critical events such as centrosome duplication and DNA synthesis initiation at the G1-S transition, modulating G2 progression and finely tuning the balance between cellular proliferation, death, and DNA repair in human embryonic stem cells. Activated sequentially by cyclin E and cyclin A2, CDK2 regulates the transition from S phase to mitosis. Notably, its phosphorylation of EZH2 is implicated in maintaining H3K27me3 and epigenetic gene silencing. CDK2's involvement extends to DNA damage responses, where it regulates the G1-S phase checkpoint, phosphorylates BRCA2, and modulates homologous recombination-dependent repair. Furthermore, CDK2 participates in diverse signaling pathways, including vitamin D-mediated growth inhibition, NO-mediated signaling, and the phosphorylation of substrates such as FOXP3 and ERCC6, highlighting its multifaceted role in cellular physiology.

The kinase activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
