Genomic-profiles and reporters reveal that the three-nucleotide ‘words’ read by the ribosome, codons, have a strong effect on mRNA stability, impacting the homeostatic mRNA and protein levels in human cells.
Study of TbAQP2 adaptations and substrate interactions shows how this aquaglyceroporin enables cellular entry of large antimicrobial agents in Trypanosoma brucei.
The coexistence of ancestral and innovative functions is possible and fosters evolutionary innovation in events involving the acquisition of whole protein domains.
In the Drosophila central brain, synaptic connectivity extracts visual-spatial information from the axons of looming sensitive LC6 neurons that terminate in a glomerulus with minimal retinotopy.
The contractile ring actin binding proteins tropomyosin Cdc8 and a-actinin Ain1 synergize to effectively compete with the endocytic actin patch protein fimbrin Fim1 for associating with F-actin networks.
The pro-apoptotic BH3-protein Bim contains two distinct binding sites for anti-apoptotic proteins that together confer resistance of Bim/Bcl-2 and Bim/Bcl-XL complexes to BH3-mimetic drugs under development for use in humans.
Mapping of 30 general RNA degradation factors onto the yeast transcriptome provides the global distribution of factors for RNA turnover and surveillance in a eukaryotic cell.
Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.
