Polyadenylation refers to the cleavage of a sequence at the 3′ end of the pre-mRNAs and addition of a stretch of adenine residues. From:Molecular Medical Microbiology (Third Edition),2024 Add to Mendeley Also in subject areas: Biochemistry, Genetics and Molecular Biology ...

Novel methods to sequence RNA 3′ ends have generated comprehensive catalogues of polyadenylation (poly(A)) sites; their analysis using innovative computational methods has revealed how poly(A) site choice is regulated by core RNA 3ʹ end processing factors, such as cleavage factor I and ...

Furthermore, a review of sequence data from animal mitochondrial genomes suggests that only tRNAs whose discriminator bases are adenosines tend to have genes that overlap with downstream genes. Thus, polyadenylation seems to be a major component of the RNA editing machinery that affects overlapping ...
SHORT SEQUENCE ELEMENTPoly(A) tail elongation after export of an messenger RNA (mRNA) to the cytoplasm is called cytoplasmic polyadenylation. It was first discovered in oocytes and embryos, where it has roles in meiosis and development. In recent years, however, has been implicated in many ...
These sequences fall into three families [57]: canonical poly(A) polymerases, non-canonical poly(A) polymerases and bacterial-type PAPs. The four cPAPs are involved in 3′ end formation of RNAs Poly(A)…or poly(U) polymerases? At least one member of the ncPAP family in Arabidopsis, ...
