RT Journal Article SR Electronic T1 Structure of G Protein–Coupled Receptors and G Proteins JF Science's STKE JO Sci. STKE FD American Association for the Advancement of Science SP tr10 OP tr10 DO 10.1126/stke.2762005tr10 VO 2005 IS 276 A1 Iyengar, Ravi YR 2005 UL http://stke.sciencemag.org/content/2005/276/tr10.abstract AB This Teaching Resource provides lecture notes and slides for a class covering the structure and function of G protein–coupled receptors and is part of the course "Cell Signaling Systems: A Course for Graduate Students." The lecture begins with a discussion of the crystal structure of rhodopsin and G protein subunits and then proceeds to describe the molecular mechanisms of receptor activation and the subsequent release of G proteins.
