Background Many bacterial extracytoplasmic proteins are stabilized by intramolecular disulfide bridges that are formed post-translationally between their cysteine residues. This protein modification plays an important role in bacterial pathogenesis, and is facilitated by the Dsb (disulfide bond) family of the redox proteins. These proteins function in two parallel pathways in the periplasmic space:...
Members of the regulator of G protein signaling 7 (RGS7) (R7) family and Gβ5 form obligate heterodimers that are expressed predominantly in the nervous system. R7-Gβ5 heterodimers are GTPase-activating proteins (GAPs) specific for Gi/o-class Gα subunits, which mediate phototransduction in retina and the action of many modulatory G protein-coupled receptors (GPCRs) in brain. Here we have focused on...
