Relating form and function of EF-hand calcium binding proteins.

ABSTRACT: The EF hand, a helix-loop-helix structure, is one of the most common motifs found in animal genomes, and EF-hand Ca(2+)-binding proteins (EFCaBPs) are widely distributed throughout the cell. However, researchers remain confounded by a lack of understanding of how peptide sequences code for specific functions and by uncertainty about the molecular mechanisms that enable EFCaBPs to distinguish among many diverse cellular targets. Such knowledge could define the roles of EFCaBPs in health and disease and ultimately enable control or even design of Ca(2+)-dependent functions in medicine and biotechnology. In this Account, we describe our structural and biochemical research designed to understand the sequence-to-function relationship in EFCaBPs. The first structural goal was to define conformat
