描述

一般說明

A highly basic, cell-permable, nonapeptide that acts as a selective myosin light chain kinase (MLCK) inhibitor (IC₅₀ = 50 nM). Does not block calmodulin (CaM) or inhibit the kinase activities of Ca²⁺/calmodulin kinase II (CaMKII) or protein kinase A (PKA). Inhibition is competitive with respect to substrate (K_i = 52 nM). Displays mixed mode inhibition with respect to ATP.

A highly basic, cell-permeable, nonapeptide that acts as a selective Myosin Light Chain Kinase (MLCK) inhibitor (IC₅₀ = 50 nM). The inhibition is competitive with respect to the peptide substrate (K_i = 52 nM) and displays a mixed mode of inhibition with respect to ATP. Does not interfere with kinase activation by calmodulin (CaM), nor does it inhibit the activities of CaMKII and PKA.
