Summary
Enables troponin T binding activity. Involved in regulation of muscle contraction and slow-twitch skeletal muscle fiber contraction. Part of troponin complex. Human ortholog(s) of this gene implicated in nemaline myopathy 5. Orthologous to human TNNT1 (troponin T1, slow skeletal type). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
