Predicted to enable troponin T binding activity. Predicted to contribute to actin binding activity. Predicted to be involved in positive regulation of transcription, DNA-templated; regulation of muscle contraction; and striated muscle contraction. Predicted to be located in nucleus. Predicted to be part of troponin complex. Is expressed in several structures, including alimentary system; diaphragm; eyelid epithelium; hindlimb muscle; and integumental system. Used to study distal arthrogryposis. Human ortholog(s) of this gene implicated in arthrogryposis multiplex congenita and distal arthrogryposis type 2B1. Orthologous to human TNNI2 (troponin I2, fast skeletal type). [provided by Alliance of Genome Resources, Apr 2022]
