Tnnc1 Gene Summary [Rat]
Enables calcium ion binding activity. Involved in cardiac muscle contraction; diaphragm contraction; and response to metal ion. Located in contractile muscle fiber. 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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Tnnc1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
