Predicted to enable FATZ binding activity; actin binding activity; and telethonin binding activity. Predicted to be involved in several processes, including negative regulation of calcineurin-NFAT signaling cascade; sarcomere organization; and skeletal muscle fiber adaptation. Predicted to be active in Z disc and actin cytoskeleton. Human ortholog(s) of this gene implicated in hypertrophic cardiomyopathy 16. Orthologous to human MYOZ2 (myozenin 2).
