Interactions between the voltage sensor and intracellular domains modulate voltage-dependent gating and calmodulin inhibition in the voltage-gated potassium channel Eag1.
Unloading the polymerase sliding clamp PCNA from DNA by Elg1 promotes recombination at the RTS1 replication fork barrier by limiting Fbh1 and Srs2 activity.
The exon junction complex regulates the cell polarity determinant Discs large 1, which acts independently from its role in cell polarity to protect Dishevelled protein from lysosomal degradation in Wingless/Wnt signaling.
FERONIA receptor kinase interacts with phosphatidylinositol-anchored proteins LORELEI and LLG1 to ensure its proper functional location in the cell membrane and engages them as co-receptors on the cell surface to mediate a broad spectrum of growth and signaling processes.
Discs large homologue 1 (Dlg1) activates beta-catenin (i.e., canonical Wnt) signaling in CNS endothelial cells to regulate retinal angiogenesis and the development and maintenance of the blood-brain and blood-retina barriers.
Syntaxin 4 regulates retrograde signaling in the postsynaptic compartment at Drosophila synapses by controlling trafficking of Neuroligin and Synaptotagmin 4 cargo.
Neuroligin 1 is a critical adhesion molecule which organizes AMPA receptor nanodomains in close vicinity to pre-synaptic release sites, and whose genetic or chemical disruption severely impairs synaptic transmission properties.
Whereas in a paradigmatic structure an SM protein chaperone clamps its client SNARE shut, a second structure demonstrates that an SM protein can also hold its SNARE open to promote assembly.
The occupation of a sub-pocket near the Na+-binding site in D2R by the Na+-insensitive antagonists is the structural basis for their greater inverse agonism than that of the Na+-sensitive ligands.
