Is calmodulin found in muscle tissue
Did you know?
Calmodulin (CaM) (an abbreviation for calcium-modulated protein) is a multifunctional intermediate calcium-binding messenger protein expressed in all eukaryotic cells. It is an intracellular target of the secondary messenger Ca , and the binding of Ca is required for the activation of calmodulin. Once bound to Ca , calmodulin acts as part of a calcium signal transduction pathway by modifying … WebAbstract. The purpose of this review is to describe the importance of calmodulin as a mediator of the effects of calcium ions in living systems, particularly in the process of skeletal muscle contraction. Calmodulin is a low molecular weight, acidic, calcium binding protein which mediates the Ca2+ regulation of a wide range of physiological ...
