Enables 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 located in sarcomere. Predicted to be active in Z disc and actin cytoskeleton. Implicated in hypertrophic cardiomyopathy 16.
RGD Description
The protein encoded by this gene belongs to a family of sarcomeric proteins that bind to calcineurin, a phosphatase involved in calcium-dependent signal transduction in diverse cell types. These family members tether calcineurin to alpha-actinin at the z-line of the sarcomere of cardiac and skeletal muscle cells, and thus they are important for calcineurin signaling. Mutations in this gene cause cardiomyopathy familial hypertrophic type 16, a hereditary heart disorder. [provided by RefSeq, Aug 2011]
