Calmodulin Binding Protein (CBP) epitope tags are found in several E. coli expression vectors. Calmodulin (CaM), a small 17 kDa ubiquitous Ca2+ binding protein, acts as an intracellular Ca2+ receptor and transduces Ca2+ transients, usually in response to growth factors. It mediates the activity of a number of Ca2+ regulating enzymes, including protein kinases, phosphatases, nitric oxide synthases, and phosphodiesterase. Calmodulin is the principal intracellular calcium receptor. It is an acidic protein of 148 residues, and upon binding Ca2+, it in turn binds to short peptide sequences of many target proteins. Such interaction is thought to induce a conformational change on the target, resulting in its activation. Targets include the constitutively expressed nitric oxide synthases, the CaM kinases, and PP2B/Calcineurin.

The molecular weight is related to the tagged protein.
