Myosin light chain kinase 3 also known as MYLK3, is an enzyme which in humans is encoded by the MYLK3 gene.^[5]^[6]

Function

Phosphorylation of cardiac myosin heavy chains (see MYH7B) and light chains (see MYL2) by a kinase, such as MYLK3, potentiates the force and rate of cross-bridge recruitment in cardiac myocytes.^[7]
