Cyclin-dependent kinase 2 - Wikipedia

WebCDK2 is a member of the Cyclin‐Dependent Kinase family that is ubiquitously expressed. CDK2 is a catalytic subunit of the cyclin‐dependent protein kinase complex, whose activity is restricted to the G1‐S phase, and essential for cell cycle G1/S phase transition. Cyclin-dependent kinase 2, also known as cell division protein kinase 2, or Cdk2, ... Cdk2 is active during G 1 and S phase of the cell cycle, and therefore acts as a G 1-S phase checkpoint control. Prior to G 1 phase, levels of Cdk4 and Cdk6 increase along with cyclin D. See more Cyclin-dependent kinase 2, also known as cell division protein kinase 2, or Cdk2, is an enzyme that in humans is encoded by the CDK2 gene. The protein encoded by this gene is a member of the cyclin-dependent kinase See more Cyclin-dependent kinase 2 is structured in two lobes. The lobe beginning at the N-terminus (N-lobe) contains many beta sheets, while the C-terminus lobe (C-lobe) is rich in alpha helices.

WebS phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G 1 phase and G 2 phase. ... During early S-phase, the cyclin E-Cdk2 complex phosphorylates NPAT, a nuclear coactivator of histone transcription. CDK levels remain relatively constant throughout the cell cycle and most regulation is post-translational. Most knowledge of CDK structure and function is based on CDKs of S. pombe (Cdc2), S. cerevisiae (CDC28), and vertebrates (CDC2 and CDK2). The four major mechanisms of CDK regulation are cyclin binding, CAK phosphorylation, regulatory inhibitory phosphorylation, and bindin…
