Predicted to enable several functions, including RNA polymerase II-specific DNA-binding transcription factor binding activity; protein C-terminus binding activity; and troponin I binding activity. Predicted to be involved in protein phosphorylation; regulation of heart contraction; and regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm. Predicted to be active in nucleus. Orthologous to several human genes including FPGT-TNNI3K (FPGT-TNNI3K readthrough). [provided by Alliance of Genome Resources, Apr 2022]
