POF shows a desires getting exons.
Splicing is commonly considered a procedure that takes place shortly after transcription. However, cotranscriptional splicing was envisioned within the Drosophila more twenty five years in the past (51). New studies have revealed that cotranscriptional splicing is far more well-known than was once felt (52) and possess you to definitely splicing may start since good cotranscriptional knowledge and you may continue posttranscriptionally (6, 50). Ergo, the fresh new strong exon prejudice reported the following is compatible with POF joining to help you nascent RNAs. Cotranscriptional splicing is thought to confidence cooperation ranging from exon recognition and the rates from transcription by RNP2. Just like the POF was associated with nascent RNAs, this reduction in the pace off transcription more than exons carry out define the fresh exon prejudice noticed from the chromatin peak inside Processor-processor chip studies (27).
After that, it has been found your occurrence off nucleosomes try highest contained in this exons; they may therefore function as rate european vs american women shocks so you’re able to reduce the RNP2 elongation rate (62, 63, 73)
Since the POF presumably attach in order to nascent RNA via the RRM1 domain name, it is interesting to look at hypothetical mechanisms for which POF might control the expression away from genetics into the chromosome cuatro.
