G protein-coupled receptor - Wikipedia
G protein-coupled receptors (GPCRs), also known as seven- (pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptors, and G protein-linked receptors (GPLR), form a large group of evolutionarily related proteins that are cell surface receptors that detect molecules outside the cell and activate cellular res...
Biochemistry, G Protein Coupled Receptors - StatPearls - NCBI Bookshelf
Jul 30, 2023 · G protein-coupled receptors (GPCRs) are integral membrane proteins that form the fourth largest superfamily in the human genome. GPCRs were named for their common ability to associate with heterotrimeric G proteins (Gαβγ).

Apr 8, 2024 · G-protein coupled receptors (GPCRs) are a diverse family of receptors found in a huge range of tissues throughout the body. They function to respond to a wide variety of extracellular signals, such as hormones or neurotransmitters, and trigger intracellular signalling cascades, which regulate a wide range of bodily functions.
G Protein-Coupled Receptors: A Century of Research and Discovery
Jun 21, 2024 · GPCRs (G protein-coupled receptors), also known as 7 transmembrane domain receptors, are the largest receptor family in the human genome, with ≈800 members. GPCRs regulate nearly every aspect of human physiology and disease, thus serving as important drug targets in cardiovascular disease.
