Transcriptional regulation evolves at indistinguishable rates in mammals, birds and insect lineages despite large differences in underlying rates of sequence evolution.

Distinct binding of viral proteins to the same region on the nucleosome surface can result in contrasting changes to higher-order chromatin structure in the host cell.

The budding yeast kinesin Kip2 is a polymerase that uses its processive motility in a positive feedback loop to promote microtubule growth.

Unanticipated rearrangements in the nitrogenase active site establish the dynamic nature of the FeMo-cofactor during catalysis.

Palmitate turnover is controlled by distinct enzyme families with different specificities.

The phosphatase Fcp1 inactivates Greatwall kinase at the end of mitosis.

Temporally close events share a common timestamp regardless of the spatial context in which they occur.

The protozoan parasite Trypanosoma brucei gambiense has undergone recent clonal evolution that reveals the theoretically predicted Meselson effect at a genome-wide level.

Fly vision depends on a member of the SLC22 transporter family for recycling the histamine neurotransmitter following its uptake by glia and its modification into the transport metabolite carcinine.

Protein structures with complex topologies can be designed by recombining small independently folded domains.
