2. Figure 1
Introns Can Be Spliced Immediately following Synthesis by RNA Polymerase II
The splicesome (PDB ID 3JB9) is shown in yellow and RNA polymerase II (PDB ID 5C4A) is shown in blue. The catalytic centers are marked with colored dots that are about 95 Å apart. Carrillo Oesterreich et al. (2016) use single-molecule sequencing approaches to demonstrate that the splicing reaction can occur immediately after the 3′SS plus ∼27 nt of exon have been made by RNA polymerase II. This figure shows 34 nt (represented in green) between the branched A in the spliceosome and the 3′ end of the nascent pre-mRNA site in the polymerase active site. The image portrays the relative sizes and proximity of the spliceosome and RNA polymerase II as the fastest co-transcriptionally spliced introns are processed.
