'''Molecular basis of Box C/D RNA-protein interaction: co-crystal structure of the Archaeal sRNP intiation complex'''<br />


==Overview==
==Molecular basis of Box C/D RNA-protein interaction: co-crystal structure of the Archaeal sRNP intiation complex==
We have determined and refined a crystal structure of the initial assembly, complex of archaeal box C/D sRNPs comprising the Archaeoglobus fulgidus, (AF) L7Ae protein and a box C/D RNA. The box C/D RNA forms a classical, kink-turn (K-turn) structure and the resulting protein-RNA complex serves, as a distinct platform for recruitment of the fibrillarin-Nop5p complex., The cocrystal structure confirms previously proposed secondary structure, of the box C/D RNA that includes a protruded U, a UU mismatch, and two, sheared tandem GA base pairs. Detailed structural comparisons of the AF, L7Ae-box C/D RNA complex with previously determined crystal structures of, L7Ae homologs in complex with functionally distinct K-turn RNAs revealed a, set of remarkably conserved principles in protein-RNA interactions. These, analyses provide a structural basis for interpreting the functional roles, of the box C/D sequences in directing specific assembly of box C/D sRNPs.
