What does GPCR mean?
INTRODUCTION G protein coupled receptors (GPCRs) represent the largest family of membrane proteins in the human genome and the richest source of targets for the pharmaceutical industry. There has been remarkable progress in the field of GPCR biology during the past two decades.
How many GPCRs are there in the human genome?
G protein coupled receptors (GPCRs) represent the single largest class of membrane proteins in the human genome. A recent and detailed analysis of the human genome reveals over 800 unique GPCRs, of which approximately 460 are predicted to be olfactory receptors [5].
What are G-protein-coupled receptors (GPCRs)?
Various ligands use G-protein-coupled receptors (GPCRs) to stimulate membrane, cytoplasmic and nuclear targets. GPCRs interact with heterotrimeric G proteins composed of α, β and γ subunits that are GDP bound in the resting state.
Why is rhodopsin better than other GPCRs?
Rhodopsin is better suited for structural studies than most other GPCRs because it is possible to obtain large quantities of highly enriched protein from bovine retina. Rhodopsin is also a remarkably stable GPCR, retaining function under conditions that denature many other GPCRs.
