  ABSTRACT  
 
Recoverin is a Ca2+-regulated signal transduction modulator found in vertebrate retina that has been shown to undergo dramatic conformational changes upon Ca2+ binding to its two functional EF-hand motifs. To elucidate the differential impact of the N-terminal myristoylation as well as occupation of the two Ca2+ binding sites on recoverin structure and function, we have investigated a non-myristoylated E85Q mutant exhibiting virtually no Ca2+ binding to EF-2. Crystal structures of the mutant protein as well as the non-myristoylated wild-type have been determined. Although the non-myristoylated E85Q mutant does not display any functional activity, its three-dimensional structure in the presence of Ca2+ resembles the myristoylated wild-type with two Ca2+ but is quite dissimilar from the myristoylated E85Q mutant. We conclude that the N-terminal myristoyl modification significantly stabilizes the conformation of the Ca2+-free protein (i.e. the T conformation) during the stepwise transition toward the fully Ca2+-occupied state. On the basis of these observations, a refined model for the role of the myristoyl group as an intrinsic allosteric modulator is proposed.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
