Tnni1 Gene Summary [Rat]
Predicted to enable actin binding activity. Predicted to be involved in cardiac muscle contraction and skeletal muscle contraction. Predicted to act upstream of or within transition between fast and slow fiber and ventricular cardiac muscle tissue morphogenesis. Part of troponin complex. Orthologous to human TNNI1 (troponin I1, slow skeletal 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 Tnni1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
