Myosin light chain kinase 2 also known as MYLK2 is an enzyme which in humans is encoded by the MYLK2 gene.[5]
Function
This gene encodes a myosin light chain kinase, a calcium / calmodulin dependent enzyme, that is exclusively expressed in adult skeletal muscle.[6] The MYLK2 gene expresses skMLCK more prevalently in fast twitch muscle fibers as compared to slow twitch muscle fibers. Calmodulin is composed of two terminal domains (N,C) each containing two E-F hand motifs that bind to Ca2+. Upon saturation of Ca2+, Calmodulin undergoes a conformation change allowing it to bind with a target protein such as skMLCK. An image depicting a similar complex (sdCen/skMLCK2) is shown under myosin light chain kinase. This binding to skMLCK increases the affinity of Ca2+ and ultimately leads to a sustained muscle action.[7]
Clinical significance
Mutations in the MYLK2 gene have been linked to midventricular hypertrophic cardiomyopathy.[5]
