Co-transcriptional splicing at nucleotide resolution

Access through your institution Buy or subscribe The sequencing methods provide single-molecule information at nucleotide resolution on the progression of splicing as a function of Pol II

position along the gene. In single-molecule intron tracking (SMIT), nascent RNA is purified and a linker is ligated to the 3′ ends of the RNA molecules to mark the position of Pol II,

followed by PCR of the nascent RNA using exon-specific 5′-end primers and massively parallel paired-end sequencing. The authors performed SMIT on 87 intron-containing genes in budding yeast

and found that a substantial fraction of their transcripts were already spliced when Pol II was positioned just downstream of 3′ splice sites (3′SS). This was unexpected, as previously

published data indicated that splicing might occur when Pol II is ∼1,000 nt downstream of introns. > onset of splicing ... was calculated to occur when Pol II was only > 26 ±1 nt 

downstream of the 3′SS This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Subscribe to this journal Receive 12 print issues
