An intriguing feature of recoverin is a cluster of charged residues at its C terminus, the functional significance of which is largely unclear. To elucidate the impact of this segment on recoverin structure and function, we have investigated a mutant lacking the C-terminal 12 amino acids. Whereas in myristoylated recoverin the truncation causes an overall decrease in Ca(2+) sensitivity, results for the non-myristoylated mutant indicate that the truncation primarily affects the high affinity EF-hand 3. The three-dimensional structure of the mutant has been determined by x-ray crystallography. In addition to significant changes in average coordinates compared with wild-type recoverin, the structure provides strong indication of increased conformational flexibility, particularly in the C-terminal domain. Based on these observations, we propose a novel role of the C-terminal segment of recoverin as an internal modulator of Ca(2+) sensitivity.}, keywords = {Animals / Base Sequence / Calcium Signaling: physiology / Cattle / Crystallography, X-Ray / DNA Primers: genetics / Kinetics / Models, Molecular / Mutagenesis, Site-Directed / Protein Structure, Quaternary / Recombinant Proteins: chemistry / Recombinant Proteins: genetics / Recombinant Proteins: metabolism / Recoverin: chemistry / Recoverin: genetics / Recoverin: metabolism / Rod Cell Outer Segment: metabolism / Sequence Deletion / Surface Plasmon Resonance / DNA Primers (NLM Chemicals) / RCV1 protein, Bos taurus (NLM Chemicals) / Recombinant Proteins (NLM Chemicals) / Recoverin (NLM Chemicals) / J (WoSType)}, cin = {IBI-2}, ddc = {570}, cid = {I:(DE-Juel1)VDB58}, pnm = {Funktion und Dysfunktion des Nervensystems}, pid = {G:(DE-Juel1)FUEK409}, shelfmark = {Biochemistry $\&$ Molecular Biology}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:17015448}, UT = {WOS:000242477100036}, doi = {10.1074/jbc.M603700200}, url = {https://juser.fz-juelich.de/record/54334}, }
