7-Transmembrane receptors

7-Transmembrane receptors (7-TM receptors), also known as G protein-coupled receptors, or GPCRs, are integral membrane proteins that contain seven membrane-spanning helices.  Many endogenous peptides activate G protein-coupled receptors.

GPCRs constitute the largest and most diverse protein family in the human genome with over 800 members identified to date.  They play critical roles in numerous cellular and physiological processes, including cell proliferation, differentiation, neurotransmission, development and apoptosis.  Aberrant receptor activity has been demonstrated in numerous disorders, and as a result GPCRs have become a very successful drug target class in pharmaceuticals treating a wide variety of indications such as pain, inflammation, neurobiological and metabolic diseases.
