The major cytosolic yeast peroxiredoxin Tsa1 controls aging and H2O2-resistance by inhibiting protein kinase A through a conserved cysteine in the catalytic subunit activation loop and not by scavenging H2O2.
Diverse sophisticated phylogenetic analyses update the phylogeny of the Alphaproteobacteria and show that the parasitic Holosporales is a derived group within the Rhodospirillales order which comprises primarily free-living alphaproteobacteria.
High-resolution GPS data revealed a quadratic relationship between group size and movement, with vulturine guineafowl groups of intermediate size exhibiting the largest home-range size and greater variation in site use.
Knockout of both latrophilin-2 and latrophilin-3 from Purkinje cells in mice selectively impairs parallel-fiber synapses, revealing a redundant but critical function for latrophilins at specific synapses.
Whole endosome recording shows that chloride interacts with vesicular glutamate transporters as both allosteric activator and permeant ion, and although the mode of permeation differs, chloride and glutamate use a related conduction pathway.
