Cyclin dependent kinase 2 (complex with cyclin A)

Synonyms: cell division protein kinase 2

Family: CMGC

CDK2 is a cyclin dependent protein kinase, which activity is restricted to the G1-S phase of the cell cycle. Originally it was thought that CDK2 is responsible for S phase initiation and progression, but it was shown that Cdk1 can take over Cdk2’s function in its absence in vivo1. However, Cdk2 is indefensible for proper DNA damage repair – it acts upstream in the DNA damage pathway and is involved in the activation of DNA repair proteins.

CDK2-CYCLINA kinase assay is run on mobility shift microfluidics platform (Caliper), which provides best in industry quality of data. We routinely run services associated with this kinase including: screening, profiling, dose-response studies and kinetic measurements. Please contact us for more information.
