Anti-troponin T type 1 (skeletal, slow) antibodies enable researchers to detect and measure the troponin T type 1 (skeletal, slow) antigen in biological samples. This target is a reported synonym of the TNNT1 gene, which encodes troponin T1, slow skeletal type. This protein is known to function in muscle contraction, among other biological roles. The human version of troponin T type 1 (skeletal, slow) has a canonical amino acid length of 278 residues and a protein mass of 32.9 kilodaltons, although 3 isoforms have been identified. It is reported to be notably expressed in the skeletal muscle. Other names for this target antigen include ANM, ANM, and NEM5.
