CDK2, CCNA2, Active, Recombinant, Human, GST-Tag (Cyclin-Dependent Kinase 2, Cell Division Kinase 2, p33 Protein Kinase, CDKN2/Cyclin-A2, Cyclin-A, CCN1, CCNA)

CDK2 is a member of the Ser/Thr protein kinase family. This protein kinase is highly similar to the gene products of S. cerevisiae cdc28, and S. pombe cdc2. It 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. This protein associates with and is regulated by the regulatory subunits of the complex including cyclin A or E, CDK inhibitor p21Cip1 (CDKN1A) and p27Kip1 (CDKN1B). Its activity is also regulated by its protein phosphorylation.\n\nCyclin-A2 (CCNA2) is a member of the Cyclin family which act as regulators of CDK kinases. CCNA2 is essential for the control of the cell cycle at the G1/S (start) and the G2/M (mitosis) transitions.\n\nSource:\nRecombinant corresponding to aa1-298 from human CDK2 and aa174-432 from human CyclinA2 fused to His-GST tags at N-terminal, coexpressed in a baculovirus Sf9 insect cell expression system.\n\nMolecular Weight:\nCDK2: ~61kD; CyclinA2: ~75kD\n\nApplications:\nSuitable for use in the study of enzyme kinetics, screening inhibitors, and selectivity profiling. Other applications not tested.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nSpecific Activity:\n~390pmol/min/ug\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only.
