SNORD36Bsmall nucleolar RNA, C/D box 36B
snoid : SR0000362
Length : 71
Abstract : Homo sapiens C/D box snoRNA U36B. This snoRNA is an human orthologue of chicken U36 snoRNA, initially characterized by a bioinformatics search for C/D motives in a vertebrate intron database (Nicoloso et al. 1996). It is predicted to guide the 2'O-ribose methylation of 18S rRNA A668. U36B shares the same host gene with the C/D box snoRNAs U36A, U36C and U24 (RPL7A). U36B is predicted to guide the methylation of both 18S rRNA A668 (human numbering) and 28S rRNA A3703 (as U36C). In primates, progressive mutations in the rRNA anti-sense sequence have suppressed the guiding function for 28S rRNA A3703. The proposed nomenclature of vertebrate U36A, B and C is based on sequence alignments rather than position in the conserved RPL7A host gene.
