WebSmall nucleolar RNPs (snoRNPs) are responsible for the processing and modification of ribosomal RNAs in the nucleolus through methylation and pseudouridylation. 34 SnoRNPs are divided into two classes—the box C/D class and the H/ACA class—both of which are required for these rRNA-processing events ( Fig. 7.1 ). WebIt is shown that, like host snRNPs, HSURs use the SMN (survival of motor neurons) complex to assemble Sm cores, and that infectious agents that engage theSMN complex …
