Article Synopsis
- Extrachromosomal elements like organelles, viruses, and plasmids are vital for cell survival, relying on host or intrinsic RNA polymerases for transcription.* -
- This study focuses on yeast Kluyveromyces lactis, which has linear viral-like elements with unique two-subunit RNA polymerases, revealing how these components interact and function together.* -
- Researchers identify important sequences for mRNA processing and determine that VLE RNA polymerase is evolutionarily related to that of poxviruses, suggesting a shared ancestry in their transcription mechanisms.*
Alternative polyadenylation is an important and pervasive mechanism that generates heterogeneous 3'-termini of mRNA and is considered an important regulator of gene expression. We performed bioinformatics analyses of ESTs and the 3'-UTRs of the main transcript splice variants of the translational initiation factor eIF4E1 and its family members, eIF4E2 and eIF4E3. This systematic analysis led to the prediction of new polyadenylation signals.

- The study investigates the localization of different eIF4E protein isoforms, specifically eIF4E2 and eIF4E3, which have received less attention compared to the well-studied eIF4E1.
- eIF4E3_A was found to localize to stress granules during stress conditions like heat shock and arsenite exposure but does not localize to processing bodies, while eIF4E3_B does not localize to stress granules at all.
- The findings suggest that different eIF4E isoforms and their variants play unique roles in cellular stress responses by showing distinct patterns of localization and interactions with other translation initiation factors.
