Fast skeletal muscle troponin T (fTnT) is a protein that in humans is encoded by the TNNT3 gene.

The TNNT3 gene is located at 11p15.5 in the human genome, encoding the fast skeletal muscle isoform of troponin T (fsTnT). fsTnT is an ~31-kDa protein consisting of 268 amino acids including the first methionine with an isoelectric point (pI) of 6.21 (embryonic form). fsTnT is the tropomyosin-binding and thin filament anchoring subunit of the troponin complex in the sarcomeres of fast twitch skeletal muscle. TNNT3 gene is specifically expressed in vertebrate fast twitch skeletal muscles.
