WebThin filament proteins The thin filaments contain three different proteins—actin, tropomyosin, and troponin. The latter is actually a complex of three proteins. Actin, which constitutes about 25 percent of the protein of myofilaments, is the major component of the thin filaments in muscle.
WebIncreased ADP sensitivity in IDCM, HCMsmn, and MYH7(mut) was caused by low phosphorylation of myofilament proteins, as it was normalized to donors by protein kinase A (PKA) treatment Troponin exchange experiments in a TNNT2(mut) sample corrected the abnormal actin-myosin blockade.
