Study of TbAQP2 adaptations and substrate interactions shows how this aquaglyceroporin enables cellular entry of large antimicrobial agents in Trypanosoma brucei.
In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.
Through visualization of directly-labeled RhoGTPase both in vitro and in vivo, RhoGDI is found to spatiotemporally regulate RhoGTPase activity through the extraction of active RhoGTPase.
ER-resident chaperones and cargo receptors make excursions to the cell surface and endocytic compartments when they accompany misfolded clients to lysosomes for degradation.
ME31B is a general repressor of gene expression in the Drosophila early embryo, repressing translation before the maternal-to-zygotic transition and stimulating mRNA decay after activation of the zygotic genome.
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.
A new optical tweezers assay sheds light on the mechanism of cooperation and force generation by the subunits of RecBCD, critical for the repair of double strand breaks in bacteria.
