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

TNNT3 gene is located in 11p15.5 in the region of the human genome encoding the fast skeletal muscle isoform of troponin T fsTnT. fsTnT is the ~31-KDA protein, consisting of 268 amino acids including the first methionine with the isoelectric point of intersection 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 specifically expressed in vertebrate fast twitch skeletal muscle.
