Dhh1, Pat1, and Lsm1 target subsets of cellular mRNAs for decapping via interactions of these regulatory proteins with the C-terminal domain of Dcp2, the catalytic component of the decapping enzyme.

An integrated biochemical and evolutionary analysis shows how enzyme specificity evolves after gene loss during genome decay, implicating relaxation of purifying selection as a driving force for functional divergence.

The yeast mRNA decapping enzyme Dcp1/Dcp2 repressses many genes whose products are required on poor carbon or nitrogen sources in nutrient-replete cells by mRNA decapping and degradation or translational repression, adding post-transcriptional controls to the transcriptional repression of these functions.

Non-invasive mRNA stability measurements reveal that transcript lifetime is governed by a competition with translation initiation on a transcriptome-wide level.

Development of a genomic dating method that leverages ancestry covariance patterns in a single diploid individual reveals the timing of major admixture events during the European Holocene.
Adaptations in protein synthesis and mRNA surveillance machinery enabled the malaria-causing parasite P. falciparum to efficiently and accurately translate long polyA nucleotide runs into long poly-lysine peptides.
Transcriptional regulation evolves at indistinguishable rates in mammals, birds and insect lineages despite large differences in underlying rates of sequence evolution.
