Summary: Enables actin filament binding activity. Involved in regulation of ATP-dependent activity and regulation of muscle filament sliding speed. Acts upstream of or within transition between fast and slow fiber. Predicted to be located in contractile muscle fiber. Predicted to be part of cardiac Troponin complex. Is expressed in several structures, including alimentary system; heart; liver; metanephros; and skeletal muscle. Used to study hypertrophic cardiomyopathy 13. Human ortholog(s) of this gene implicated in dilated cardiomyopathy 1Z; hypertrophic cardiomyopathy; and hypertrophic cardiomyopathy 13. Orthologous to human TNNC1 (troponin C1, slow skeletal and cardiac type). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
