Shortening of sarcomere

SpletIndeed, the initial characterization of Obscn KO mice revealed a significant shortening of the longitudinal sarcoplasmic reticulum, paralleled by decreased sAnk1.5 protein levels [ 23 ]. Interestingly, in a mirror-like image, skeletal muscle fibers of sAnk1.5 KO mice also presented a strong reduction in the sarcoplasmic reticulum volume [ 24 ]. SpletThe molecular events of muscle fiber shortening occur within the fiber’s sarcomeres (see Figure 10.10). The contraction of a striated muscle fiber occurs as the sarcomeres, …

What happens when the sarcomere contracts and shortens?

SpletAn individual sarcomere contains many paralleling actin (thin) and myosin (thick) filaments. The user of myosin and actin proteins is at the core of our current understanding of sarcomere shortening. How does get shortening happen? Information has something to do with ampere sliding interaction between actin and myosin. SpletEach sarcomere consists of alternating thick Myosin and thin Actin protein filaments. The sarcomere shortens from both sides when Actin filaments slide along the Myosin …
