Description

General description

A 17-residue peptide based on the calmodulin-binding domain of myosin light chain kinase (MLCK). Binds to calmodulin with high affinity (K_d = 6 pM). Inhibits calmodulin activation of MLCK-catalyzed phosphorylation of smooth muscle regulatory light chain(MLC).

Biochem/physiol Actions

Cell permeable: no

Kd = 6 pM in binding to calmodulin

Primary Target
Calmodulin

Product does not compete with ATP.

Reversible: no

Physical form

Supplied as a trifluoroacetate salt.

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.
