G-protein Coupled Receptor Dimerization
A growing body of evidence suggests that GPCRs exist and function as dimers or higher oligomers. The evidence for GPCR dimerization comes from biochemical, biophysical and functional studies. In addition, researchers have shown the occurrence of heterodimerization between different members of the GPCR family. Two receptors can interact with each other to make a dimer through their extracellular...
متن کاملRestructuring G-Protein- Coupled Receptor Activation
G-protein-coupled receptors serve as key signal transduction conduits, linking extracellular inputs with diverse cellular responses. These receptors eluded structural characterization for decades following their identification. A landmark structure of rhodopsin provided a basis for structure-function studies and homology modeling, but advances in receptor biology suffered from a lack of recepto...
متن کاملStructural Insights into Activation and Allosteric Modulation of G Protein-Coupled Receptors
G protein-coupled receptors (GPCRs) are cell-surface receptors that regulate neurotransmission, cardiovascular function, metabolic homeostasis, and many other physiological processes. Due to their central role in human physiology, these receptors are among the most important targets of therapeutic drugs, and are they among the most extensively studied integral membrane proteins. To better under...
متن کاملMutations in G proteins and G protein-coupled receptors in endocrine disease.
G Proteins couple receptors for diverse extracellular signals to effecters such as enzymes and ion channels. The majority of polypeptide hormones, all monoamine neurotransmitters, PGs, and even extracellular Ca’+ signal their target cells through G protein-coupled receptors (GPCR). In the past few years, mutations in G proteins and GPCR have been identified as the causes of several endocrine di...
متن کامل"Current biotechnological approaches for studying G protein coupled receptor structure, function and signaling".
Aims & Scope: G-protein -coupled receptors (GPCRs) are the largest class of cell-surface receptors and mediate most of our physiological responses to hormones, neurotransmitters, as well as being responsible for vision, olfaction and taste. They carry out a multitude of tasks in the central nervous system (CNS) and the periphery. Numerous diseases and disorders have been linked to mutations and...
