Dear student
- The contractile regulatory proteins that mask and unmask active sites in the sarcomere are troponin and tropomyosin.
- The two tropomyosin filaments run close to the actin filaments throughout its length.
- The troponin units are distributed throughout the length of tropomyosin filaments and mask the active binding sites for myosin.
- During muscle contraction, the increased calcium ion levels lead to their binding to a subunit of troponin and unmasking the active sites for myosin filaments.
