Purified Pannexin 1 channels activated by caspase cleavage in proteoliposomes reconstitute a permeation pathway for intercellular signaling molecules important in inflammation and cell clearance.
An optogenetic dual-color Ca2+-imaging approach shows how submucosal pacemaker-cells, interstitial cells of Cajal, modulate smooth-muscle responses and drive colonic motility via complex Ca2+ signaling.
Analysis of the E. coli protein DolP reveals the first dual BON-domain structure and identifies phospholipid binding as a new mechanism for protein localisation to the outer membrane division site.
Rejuvenation of corneal epithelium in homeostasis is determined by the interplay between corneal cells replicative lifespan and the spatial correlation between cell replication and cell removal.
The LINC complex has a core 6:6 structure in which KASH-binding induces head-to-head interactions between SUN trimers, suggesting force transduction between cytoskeletal and nuclear components through branched LINC complex networks.
Time-resolved and site-directed in vivo photo-crosslinking analysis of VemP allows identification of both cis- and trans-elements required for its regulated arrest-cancelation.
Models of chromosome compaction by condensins demonstrate that two-sided loop extrusion and long residence times are required for high compaction, suggesting a tight coupling between these two properties in vivo.
