Calmodulin (CaM) (an abbreviation for CALcium MODULated proteIN)'s a calcium-binding protein expressed in all eukaryotic cells. It can bind to and regulate a number of different protein targets, thereby affecting many different cellular functions. Function CaM mediates processes such as inflammation, metabolism, apoptosis, muscle contraction, intracellular movement, short-term and long-term memory, nerve growth and the immune response. CaM's expressed in many cell types and can have different s… (More on Calmodulin)
