... and the involved factors during splicing remain elusive. Recently published structures of the human C* spliceosome clarified the position of the EJC at this phase of splicing and have given insight into previously unidentified interactions between the EJC and spliceosomal proteins. Here, these new observations...

...Rebecca Hogg; Joanne C. McGrail; Raymond T. O'Keefe The NineTeen Complex (NTC) of proteins associates with the spliceosome during pre-mRNA splicing and is essential for both steps of intron removal. The NTC and other NTC-associated proteins are recruited to the spliceosome where they participate...

...Lily Novak Frazer; Verity Nancollis; Raymond T. O'Keefe Pre-mRNA splicing is an essential step in gene expression where intron regions are removed and coding exon sequences are joined to form an mRNA for translation. Splicing is catalysed by an RNA–protein complex called the spliceosome. A number...

...S.E. Butcher; D.A. Brow The spliceosome catalyses the splicing of nuclear pre-mRNA (precursor mRNA) in eukaryotes. Pre-mRNA splicing is essential to remove internal non-coding regions of pre-mRNA (introns) and to join the remaining segments (exons) into mRNA before translation. The spliceosome...

...-mRNA splicing occurs in the nucleus and is catalysed by complex ribonucleoprotein machines called spliceosomes. These molecular machines consist of several small nuclear RNA molecules and their associated proteins [together termed snRNP (small nuclear ribonucleoprotein) particles], plus multiple...
