The evolution of the light-sensitive visual pigment rhodopsin involved functional tradeoffs that may have sacrificed rod photosensitivity for active-state protein stability to mitigate phototoxicity in tetrapods, but not in fishes.

Affinity capture of polyribosomes followed by RNAseq(ACAPSeq) is a technique that harnesses massively parallel sequencing to identify protein-protein interactions from any source from which polyribosomes can be purified.

Peptidoglycan precursor synthesis occurs in both growing and non-growing regions of the mycobacterial cell surface.

Cereblon-based small-molecule degraders rely on the sequential action of ubiquitin-conjugating enzymes UBE2G1 and UBE2D3 to assemble K48-linked polyubiquitin chains on cereblon neomorphic substrates, resulting in their proteasomal degradation.

Yeast RNA helicase Ded1 stimulates ribosome recruitment of structure-laden native mRNAs in a reconstituted system by interactions between domains in Ded1 and initiation factor eIF4G that stabilizes a Ded1-eIF4F complex.

Structural and biochemical analyses of BRCT domain interactions defines TOPBP1/Rad4 selectivity for phosphorylated motifs, allowing identification of new interactions, and providing insights into assembly of different TOPBP1-scaffolded DNA repair complexes.

Genetic, structural, and biochemical analyses of IS607-family transposons shows that the DNA translocation reaction proceeds very differently from other reactions promoted by serine recombinases.

Endoplasmic reticulum proteostasis factors enhance the mutational tolerance of influenza hemagglutinin, a model secretory pathway protein and therapeutic target, particularly improving the fitness of temperature-sensitive variants.

The structure of the calcium channel Orai in an open conformation reveals a dilated pore and gives insight into mechanisms of ion permeation and calcium selectivity.

Structure, dynamics, and mutation of a gamete fusion protein and comparisons to viral homologues suggest that after trimerization the domain bearing the membrane-inserting fusion loops can pivot with respect to the trimer 3-fold axis.
