A comprehensive whole cell proteomic map describing expression time courses of >6,500 viral and cellular proteins during HIV infection identifies Vif-dependent antagonism of key cellular phosphatase PP2A.
Intersectin counterparts in yeast recruit WASP and WIP to endocytic sites to establish a robust multivalent SH3 domain-PRM interaction network which gives actin assembly onset a switch-like behavior in vivo.
Client protein-driven reversal of endoplasmic reticulum chaperone (BiP) mediated-repression is revealed as a principal component of the regulation of the unfolded protein response transducer IRE1 in cells.
The membrane proteins Reck and Gpr124 are integral components of a novel Wnt7a/Wnt7b-specific signaling complex, and there is a distinctive requirement for Wnt/β-catenin signaling in tip cells during angiogenesis in the central nervous system.
Direct modification by endogenous peroxide of a conserved cysteine in the molecular chaperone BiP decouples its ATPase and peptide-binding activities, allowing for enhanced polypeptide holdase activity during oxidative stress.
Point mutations in a ubiquitous human ATPase called p97/VCP deregulate inter-domain communication, resulting in impaired binding of an adaptor that recruits p97 to endosomal pathways and leading to a degenerative disease of bone, muscle and neurons.
