3'-UTRs and the Control of Protein Expression in Space and Time.

The noncoding elements of an mRNA influence multiple aspects of its fate. For example, 3'-UTRs serve as physical and sequence-based information hubs that direct the time, place, and level of translation of the protein encoded in cis, but often also have additional roles in trans. Understanding the information content of 3'-UTRs has been a challenge.

Coordination of Cell Cycle Progression and Mitotic Spindle Assembly Involves Histone H3 Lysine 4 Methylation by Set1/COMPASS.

Methylation of histone H3 lysine 4 (H3K4) by Set1 complex/COMPASS is a hallmark of eukaryotic chromatin, but it remains poorly understood how this post-translational modification contributes to the regulation of biological processes like the cell cycle. Here, we report a H3K4 methylation-dependent pathway in Saccharomyces cerevisiae that governs toxicity toward benomyl, a microtubule destabilizing drug. Benomyl-sensitive growth of wild-type cells required mono- and dimethylation of H3K4 and Pho23, a PHD-containing subunit of the Rpd3L complex.
