TNNT2 - troponin T2, cardiac type Gene
Also Known as CMH2; RCM3; TnTC; cTnT; CMD1D; CMPD2; LVNC6
Species: Homo sapiens
About TNNT2
This gene has 29 transcripts (splice variants), 461 orthologues, 2 paralogues and is associated with 9 phenotypes. Restricted expression toward heart (RPKM 1647.3).
Summary
This gene encodes the cardiac isoform of troponin T. The encoded protein is the tropomyosin-binding subunit of the troponin complex, which is located on the thin filament of striated muscles and regulates muscle contraction in response to alterations in intracellular calcium ion concentration. Mutations in this gene have been associated with familial hypertrophic cardiomyopathy as well as with dilated cardiomyopathy. [provided by RefSeq, May 2022]
