WebThe Calcium Release Unit Consists of Multiple Proteins on T-tubules and Sarcoplasmic Reticulum Membranes The Calcium Release Unit of muscle consists of the terminal cisternae of the sarcoplasmic reticulum and its adjacent transverse or T-tubule that is the invaginated part of the surface membrane. WebThe depolarization of the T-tubules causes the sarcoplasmic reticulum (SR), a specialized endoplasmic reticulum in muscle cells, to release calcium ions (Ca2+) into the cytoplasm of the muscle cell. The released calcium ions then bind to troponin, a protein on the actin filaments, causing a conformational change that moves tropomyosin away from the …
