Webthe 5' end, removal of introns by splicing, endonucleolytical cleavage and polyadenylation of the 3' end and editing. mRNAs are finally assembled by a central coding region which is translated to the final polypeptide and by non-coding regions at 5' and 3' ends that are not translated (untranslated regions; UTRs). WebRNA polyadenylation is regulated by PABPN1, which binds the RNA and stimulates poly(A) polymerase (PAP) activity. 48 To assess the interaction between PABPN1 and TERRA, we immunoprecipitated the PABPN1 protein and performed qRT-PCR analyses to detect TERRA transcripts (Figures 4 F and 4G). Interestingly, most TERRA subpopulations …
