MW: ~24 kDa. Recombinant full-length human Troponin1 protein was expressed in E. coli cells using an N-terminal His tag.Scientific Background: Troponin1 is a member of the tropomyosin family and regulates the calcium sensitivity of the myofibril contractile apparatus of striated muscles. Troponin1 is part of a complex with troponin T and troponin C in which Troponin1 acts as an inhibitory subunit that blocks actin-myosin interactions and thereby mediates striated muscle relaxation
