Structural diversity of calmodulin binding to its target sites

FEBS J. 2013 Nov;280(21):5551-65. doi: 10.1111/febs.12296. Epub 2013 May 13.


Calmodulin (CaM) is a ubiquitous, highly conserved, eukaryotic protein that binds to and regulates a number of diverse target proteins involved in different functions such as metabolism, muscle contraction, apoptosis, memory, inflammation and the immune response. In this minireview, we analyze the large number of CaM-complex structures deposited in the Protein Data Bank (i.e. crystal and nuclear magnetic resonance structures) to gain insight into the structural diversity of CaM-binding sites and mechanisms, such as those for CaM-activated protein kinases and phosphatases, voltage-gated Ca(2+)-channels and the plasma membrane Ca(2+)-ATPase.

Keywords: EF-hands; calcium; calmodulin; calmodulin-binding site; ion channels.
