Predicted to enable actin monomer binding activity and calcium ion binding activity. Predicted to be a structural constituent of muscle. Involved in heart contraction; heart development; and positive regulation of the force of heart contraction. Acts upstream of or within several processes, includin
g cardiac muscle contraction; heart development; and muscle cell fate specification. Located in myofibril. Is expressed in several structures, including aorta; embryo mesoderm; eye; heart; and triceps surae muscle. Human ortholog(s) of this gene implicated in familial hypertrophic cardiomyopathy; hypertrophic cardiomyopathy 10; and infantile-onset myofibrillar myopathy 12 with cardiomyopathy. Orthologous to human MYL2 (myosin light chain 2). [provided by Alliance of Genome Resources, Jul 2025]
Predicted to enable calcium ion binding activity. Predicted to be involved in cardiac muscle tissue development and heart contraction. Located in dendritic spine. Is expressed in several structures, including gastrocnemius muscle; heart; liver; uterus; and vascular system. Orthologous to human MYL7
