Assignment of the backbone1H,15N,13C NMR resonances and secondary structure of a double-stranded RNA binding domain from theDrosophilaprotein staufen

Abstract
NMR spectroscopy has been used to determine the secondary structure of one of the double-stranded RNA binding domains from the Drosophila protein staufen. The domain has an αβββα arrangement of secondary structure, with the β strands forming an antiparallel β sheet. The secondary structure differs from that found in the RNP RNA binding domain
