Myosin regulatory light chain 2 ventricular/cardiac muscle isoform is a protein that in humans is encoded by the MYL2 gene.MYL2 encodes the regulatory light chain associated with cardiac myosin beta (or slow) heavy chain. Ca+ triggers the phosphorylation of regulatory light chain that in turn triggers contraction. Mutations in MYL2 are associated with mid-left ventricular chamber type hypertrophic cardiomyopathy.
