Chemical shift assignments of calmodulin constructs with EF hand mutations.

Abstract excerpt

Calmodulin (CaM) is a ubiquitous cytosolic Ca(2+)-binding protein able to bind and regulate hundreds of different proteins. It consists of two globular domains joined by a flexible central linker region. Each one of these domains contains two EF hand pairs capable of binding to Ca(2+). Upon Ca(2+) binding CaM undergoes a conformational change exposing hydrophobic patches that interact with its intracellular...
