Summary
Class C G-protein-coupled receptors are multidomain proteins that function as dimers. This dimerization is crucial for their activation, influencing their properties and guiding drug development strategies.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- G-protein-coupled receptors (GPCRs) were traditionally viewed as monomers.
- Recent evidence suggests GPCRs can form dimers or higher-order oligomers.
- The functional significance of GPCR oligomerization remains largely unclear.
Purpose of the Study:
- To review the role of dimerization in Class C GPCRs.
- To highlight the importance of Class C GPCR dimerization for receptor activation.
- To discuss the implications of dimerization for functional properties and drug development.
Main Methods:
- Review of existing literature on Class C GPCRs.
- Analysis of structural and functional data related to GPCR dimerization.
- Integration of findings to explain the significance of dimerization.
Main Results:
- Class C GPCRs are inherently dimeric, often linked by disulfide bridges.
- Dimerization is essential for the activation mechanism of Class C GPCRs.
- Dimerization impacts specific functional characteristics of these receptors.
Conclusions:
- Class C GPCRs represent a key example of functionally significant GPCR dimerization.
- Understanding dimerization is critical for elucidating Class C GPCR function.
- GPCR dimerization offers potential targets for novel drug development.

132.2K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

17.8K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.

01:58Cooperative Allosteric Transitions
8.9K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Binding sites linkages can regulate a protein's function. For example, enzyme activity is often regulated through a feedback mechanism where the end product of the biochemical process serves as an inhibitor.
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis...

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to...
