Troponin isoform diversity in skeletal muscle may refine fiber regulation models; leaves open functional and clinical correlations.

This research aims to characterize the variations of troponin T and tropomyosin subunits in mammalian skeletal muscles.
Characterization of myofibrillar proteins from adult rabbit skeletal muscles.
Histochemical analysis of muscle fiber types and protein expression distribution.
Identification of fast and slow troponin T variants and their associated tropomyosin subunits.
Two forms of fast troponin T (TnT1f with alpha beta-Tm and TnT2f with alpha 2-Tm) were identified.
Evidence for two slow troponin T forms was found, showing variation in troponin-tropomyosin combinations.
No correlation was observed between histochemical fiber typing and the composition of calcium-regulatory complexes in individual muscle fibers.

Schachat et al. (1985) studied this question.
