Calmodulin (CaM) is a ubiquitous, calcium-binding protein that can bind to and regulate a multitude of different protein targets, thereby affecting many different cellular functions.
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 is expressed in many cell types and can have different subcellular locations, including the cytoplasm, within organelles, or associated with the plasma or organelle membranes. Many of the proteins that CaM binds are unable to bind calcium themselves, and as such use CaM as a calcium sensor and signal transducer. CaM undergoes a conformational change upon binding to calcium, which enables it to bind to specific proteins for a specific response. CaM can bind up to four calcium ions, and can undergo post-translational modifications, such as phosphorylation, acetylation, methylation and proteolytic cleavage, each of which can potentially modulate its actions.

Also reacts to wheat germ. Wide cross-reactivity expected.

Specific for both Ca2+-bound and Ca2+-free calmodulin, Mr 17 kDa. Does not recognize bovine S100-alpha, S100-beta, troponin C or parvalbumin.

Epitope: a.a. 128-148

Synthetic peptide corresponding to the 21 carboxy-terminal amino acids (128-148) of bovine calmodulin, conjugated with tyroglobulin.
