Description

Predicted to have cytoskeletal protein binding activity and protein-macromolecule adaptor activity. Involved in several processes, including animal organ development; circulatory system development; and nitric oxide biosynthetic process. Localizes to troponin complex. Is expressed in cardiac muscle; cardiovascular system; and mesoderm. Used to study hypertrophic cardiomyopathy. Human ortholog(s) of this gene implicated in intrinsic cardiomyopathy (multiple). Orthologous to human TNNT2 (troponin T2, cardiac type).
