    Background
    
    MLCK inhibitor peptide 18 is a cell-permeable inhibitor of MLCK (IC50 = 50 nM), with 4000-fold selectivity for MLCK over another closely related calmodulin (CaM)-regulated protein kinase, CaM-dependent kinase II (CaMPKII). MLCK inhibitor peptide 18 can cross cell membrane, and regulate paracellular permeability by reducing intracellular MLC phosphorylation, with the potential to restore barrier function in intestinal disease states. In addition, MLCK inhibitor peptide 18 can also inhibit chromosome-mediated cortical reorganization in mouse oocytes, as well as complement receptor-3 (CR3) mediated phagocytosis of C3bi-opsonized zymosan by mouse microglia.
