Predicted to enable identical protein binding activity and myosin heavy chain binding activity. Predicted to be a structural constituent of muscle. Involved in cardiac muscle contraction and regulation of striated muscle contraction. Located in striated muscle myosin thick filament. Human ortholog(s) of this gene implicated in familial hypertrophic cardiomyopathy; hypertrophic cardiomyopathy; and hypertrophic cardiomyopathy 4. Orthologous to human MYBPC3 (myosin binding protein C3). [provided by Alliance of Genome Resources, Apr 2022]
