Sarcoplasmic reticulum - an overview ScienceDirect Topics
The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the smooth endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca ). Calcium ion levels are kept relatively constant, with the concentration of calcium ions … Zobacz więcej The sarcoplasmic reticulum is a network of tubules that extend throughout muscle cells, wrapping around (but not in direct contact with) the myofibrils (contractile units of the cell). Cardiac and skeletal muscle cells contain … Zobacz więcej The SR contains ion channel pumps, within its membrane that are responsible for pumping Ca into the SR. As the calcium ion … Zobacz więcej Calcium ion release from the SR, occurs in the junctional SR/terminal cisternae through a ryanodine receptor (RyR) and is known as a Zobacz więcej Located within the SR is a protein called calsequestrin. This protein can bind to around 50 Ca , which decreases the amount of free Ca within the SR (as more is bound to … Zobacz więcej The breakdown of the sarcoplasmic reticulum, along with the resultant release of calcium, is an important contributor to rigor mortis, the stiffening of muscles after death.
