CDC2 Antibody – Rabbit Polyclonal

This gene encodes a member of a family of serine/threonine protein kinases that participate in cell cycle regulation. The encoded protein is the catalytic subunit of the cyclin-dependent protein kinase complex, which regulates progression through the cell cycle. Activity of this protein is especially critical during the G1 to S phase transition. This protein associates with and regulated by other subunits of the complex including cyclin A or E, CDK inhibitor p21Cip1 (CDKN1A), and p27Kip1 (CDKN1B). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

CDK2: a protein kinase of the CDK family. An important component of the cell cycle machinery. Activity of CDK2 is maximal during S phase and G2. Cdk2/cyclin E kinase activity is important for the G1 to S transition and phosphorylates the Rb protein. In S-phase, active cdk2/cyclin A complexes predominate and phosphorylate E2F, and the active cdk2 complex persists in the nucleus through G2. Part of the Rb pathway disregulated in most tumors. Target of several candidate cancer drugs. However, inhibition does not always prevent cancer cell growth, possibly due to CDK redundancy.
