| Biochem/physiol Actions: | K03861 is an ATP site-binding, cyclin-competitive, type II CDK2 inhibitor that selectively targets and locks the kinase in its inactive DFG-out conformation (CDK2 Kd = 50 nM, DFG-out stabilizing CDK2-C118L/A144C mutant Kd = 9.7 nM without vs. 134.1 nM with bound cycB; CDK2-C118L/A144C-cycA IC50 = 0.8 μM), rendering it incompatible for cyclin bining. K03861 selectively inhibits CDK2-C118L/A144C over CycA-bound wt CDK2 by in vitro kinase assay (IC50 = 0.8 vs. >10 μM) and inhibits the proliferation of immortalized multipotent otic progenitor (iMOP) murine cell line (by 81% and 92%, resepectively, at 0.1 and 1.0 μM). |
