Mechanistic insights into the role of the canonical poly(A) polymerase Pla1 in RNA surveillance by the fission yeast MTREC complex


ABSTRACT: In this study we analysed the functional relevance of the interaction between Pla1 and the MTREC complex core component Red1 using various high throughput sequencing analyses performed on different Pla1-Red1 interaction mutants.Our analyses revealed that as part of MTREC complex, Pla1 hyper-adenylates Cryptic Unstable Transcripts (CUTs) for their efficient degradation. Interestingly, our H3K9(me)2 ChIP seq. data analysis also showed us that a functional Red1-Pla1 interaction was also required for the efficient assembly of the fission yeast facultative heterochromatic islands. Together, our data suggest a complex interplay between the RNA surveillance and 3’-end processing machineries.
