Modified Method of rRNA Structure Analysis Reveals Novel Characteristics of Box C/D RNA Analogues.

ABSTRACT: Ribosomal RNA (rRNA) maturation is a complex process that involves chemical modifications of the bases or sugar residues of specific nucleotides. One of the most abundant types of rRNA modifications, ribose 2'-O-methylation, is guided by ribonucleoprotein complexes containing small nucleolar box C/D RNAs. Since the majority of 2'-O-methylated nucleotides are located in the most conserved regions of rRNA that comprise functionally important centers of the ribosome, an alteration in a 2'-O-methylation profile can affect ribosome assembly and function. One of the key approaches for localization of 2'-O-methylated nucleotides in long RNAs is a method based on the termination of reverse transcription. The current study presents an adaptation of this method for the use of fluorescently labeled p
