SnoRNP Biogenesis Meets Pre-mRNA Splicing

Abstract

In vertebrates, hundreds of small nucleolar RNAs (snoRNAs) are processed from pre-mRNA introns. In the September 1 issue of Molecular Cell, Hirose et al. (2006) demonstrate that a spliceosomal intron binding protein, IBP160, couples box C/D snoRNA processing with pre-mRNA splicing in the C1 splicing complex. © 2006 Elsevier Inc. All rights reserved.
