WebMyosin and actin filaments are laid side by side to form the cylindrical sarcomere. Sarcomeres are positioned end to end to form a myofibril.Each myofibril is surrounded by the sarcoplasmic reticulum, the specialized endoplasmic reticulum of the myocyte.The lumen of the sarcoplasmic reticulum is filled with Ca 2+ ions. Lodged between the … WebWe further show that splicing mediated by SF1 and Hrb87F is necessary for Z-disc stability and proper myofibril development, and strong knockdown of either gene results in impaired localization of kettin to the Z-disc. ... If we consider the phenotype of the strongest hairpin for each gene, 23 genes have lethal phenotypes and 9 genes have ...
