Entrez ID 7139
Gene name Troponin T2, cardiac type
Gene symbol TNNT2
Synonyms (NCBI Gene)
CMD1DCMH2CMPD2LVNC6RCM3TnTCcTnT
Chromosome 1
Chromosome location 1q32.1
Summary The protein encoded by this gene 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.
