MLCK inhibitor peptide 18 is amyosinlight chain kinase (MLCK) inhibitor with anIC₅₀of 50 nM, and inhibitsCaM kinase IIonly at 4000-fold higher concentrations.

MLCK inhibitor peptide 18 has a selective effect on peptide substrate utilization by MLCK, does not interfere with kinase activation by CaM, does not have significant inhibitory activity with the closely related CaMPKII, and does not inhibit PKA^[1].
