A structural constituent of cytoskeleton. Acts upstream of or within several processes, including cardiac muscle tissue morphogenesis; response to bacterium; and sarcomere organization. Located in sarcomere. Part of troponin complex. Is expressed in several structures, including crus of diaphragm; embryo mesenchyme; heart; musculature; and urogenital sinus. Used to study dilated cardiomyopathy 1D and hypertrophic cardiomyopathy 2. Human ortholog(s) of this gene implicated in intrinsic cardiomyopathy (multiple). Orthologous to human TNNT2 (troponin T2, cardiac type). [provided by Alliance of Genome Resources, Apr 2022]
