WebMar 12, 2024 · In cells, Tm-isoforms collectively regulate the functional role of actin filaments. Tm-isoforms have two types—(a) muscle Tm-isoforms and (b) non-muscle Tm-isoforms . The interactions between actin and myosin are controlled by these Tm-isoforms and play a pivotal role in controlling Ca ++ sensitive regulation of contraction [54,55,56]. WebApr 18, 2012 · Muscle fibers can be classified into groups based on properties such as contractile speed, myosin heavy chain (MHC) expression, and metabolic capacity [2], [3]. In general, adult mammalian muscle can contain 4 major MHC isoforms; one slow isoform (MHCI) and three fast isoforms (MHCIIa, MHCIIx, MHCIIb).
