Skeletal muscle contraction is initiated by Ca 2+ release from terminal cisternae (Somlyo et al. , [2]), the portion of the sarcoplasmic reticulum junctionally associated, via feet structures, to invaginations of the plasmalemma called the transverse tubules (Franzini-Armstrong; Kawamoto et al....
Sarco/endoplasmic reticulum–mitochondria communication and mitochondrial dynamics are essential regulators of mitochondrial function, cellular metabolism, and calcium homeostasis Sarco/endoplasmic reticulum–mitochondria contacts and mitochondrial dynamics modulate myocardial contractility and vascular smooth muscle cell...
Sarcolemmic and T-tubules are absent in scallop myocardial cells, while the sarcoplasmic reticulum forms a network of tubules extending throughout the cell. This contrasts with adductor muscle cells, in which the sarcoplasmic reticulum is situated only under the sarcolemma. Stimulus for calcium ...
Benzophenone (BP) was used as a photosensitizer to initiate lipid peroxidation in model and native biological membranes at concentrations of BP that do not perturb bilayer structure, as assessed by stearic acid spin label dynamics. Illumination of BP partitioned into sarcoplasmic reticulum membranes (...
Molecular biology of cardiac sarcoplasmic reticulum proteins: Studies on the structure and distribution of calsequestrin and phospholamban.Complementary DNA clones of cardiac calsequestrin and phospholamban were isolated and novel isoforms of both of these sarcoplasmic reticulum proteins detected. The complete ...
