The [[protein]] encoded by this gene is a member of the [[cyclin-dependent kinase]] family of [[serine/threonine-specific protein kinase|Ser/Thr protein kinases]]. This protein kinase is highly similar to the gene products of ''[[Saccharomyces cerevisiae|S. cerevisiae]]'' [[cdc28]], and ''[[Schizosaccharomyces pombe|S. pombe]]'' cdc2, also known as [[Cdk1]] in humans. It is a catalytic subunit of the [[cyclin-dependent kinase]] complex, whose activity is restricted to the G1-S phase of the [[cell cycle]], and is essential{{Citation needed|reason=Bullshit, see below.<ref name="Cdk2 knockout mice are viable">{{cite journal | vauthors = Berthet C, Aleem E, Coppola V, Tessarollo L, Kaldis P | title = Cdk2 knockout mice are viable | journal = Curr.

Cyclin-dependent kinase 2, also known as cell division protein kinase 2, is an enzyme that in humans is encoded by the CDK2 gene.[1][2]

Function

The protein encoded by this gene is a member of the cyclin-dependent kinase family of Ser/Thr protein kinases. This protein kinase is highly similar to the gene products of S. cerevisiae cdc28, and S. pombe cdc2, also known as Cdk1 in humans. It is a catalytic subunit of the cyclin-dependent kinase complex, whose activity is restricted to the G1-S phase of the cell cycle, and is essential[citation needed] for the G1/S transition. This protein associates with and is regulated by the regulatory subunits of the complex including cyclin E or A. Cyclin E binds G1 phase Cdk2, which is required for the transition from G1 to S phase while binding with Cyclin A is required to progress through the S phase. Its activity is also regulated by phosphorylation. Two alternatively spliced variants and multiple transcription initiation sites of this gene have been reported.[2]

The role of this protein in G1-S transition has been recently questioned as cells lacking Cdk2 are reported to have no problem during this transition.[3]

Inhibitors

Known CDK inhibitors are p21Cip1 (CDKN1A) and p27Kip1 (CDKN1B).[4]

Drugs that inhibit Cdk2 and arrest the cell cycle, such as GW8510 and the experimental cancer drug seliciclib, may reduce the sensitivity of the epithelium to many cell cycle-active antitumor agents and, therefore, represent a strategy for prevention of chemotherapy-induced alopecia.[5]

See also the PDB gallery below showing interactions with many inhibitors (inc Purvalanol B)

Gene regulation

In melanocytic cell types, expression of the CDK2 gene is regulated by the Microphthalmia-associated transcription factor.[6][7]

Interactions

Cyclin-dependent kinase 2 has been shown to interact with:
