Predicted to enable calcium-dependent protein binding activity and cytoskeletal protein binding activity. Predicted to contribute to actin binding activity. Involved in regulation of striated muscle contraction. Part of troponin complex. Human ortholog(s) of this gene implicated in distal arthrogryposis type 2B and distal arthrogryposis type 2B2. Orthologous to human TNNT3 (troponin T3, fast skeletal type). [provided by Alliance of Genome Resources, Apr 2022]
