Description

General description

A cell-permeable, reversible and competitive inhibitor of rat brain CaM kinase II (K_i = 370 nM). Selectively binds to the CaM binding site of the enzyme and prevents the association of CaM with CaMKII. Has no significant effects on protein kinase A activity. Induces G₁ cell cycle arrest and apoptosis in NIH/3T3 cells. A 5 mM (1 mg/399 µl) solution of KN-93 (Cat. No. 422712) in DMSO is also available.

Cell-permeable, reversible, and competitive inhibitor of rat brain Ca⁺²/calmodulin-dependent protein kinase II (K_i = 370 nM). KN-93 selectively binds to the Calmodulin (CaM) binding site of the enzyme and prevents the association of CaM with CaM Kinase II. Selectively binds to the CaM binding site of the enzyme and prevents the association of CaM with CaMKII. Has no significant effect on protein kinase A activity. Induces G₁ cell cycle arrest and apoptosis in NIH 3T3 cells.
