WebG-protein-coupled receptors (GPCRs) are the largest human receptor family and involved in virtually every physiological process. One hallmark of their function is specific coupling to selected signaling pathways. The ability to tune this coupling would make development of receptors with new capabilities possible. WebOptoXRs with improved sensitivity and tunable signaling features superior to pre-existing examples. These efforts lay the foundation for an expanded set of OptoXRs featuring Ga i/o-, Ga q-, and Ga 12/13-selective chimeras with desirable signaling features that we believe will prove to be valuable tools for the greater scientiﬁc community. WebDec 24, 2013 · Two approaches have been developed so far to control adrenergic (OptoXRs) and serotonergic (CT-tagging) signaling pathways [ 13 – 15 ]. G protein-coupled receptors (GPCRs) consist of seven transmembrane domains (TMs), which are connected via intra- and extracellular protein domains. pop the smoke
