| G-protein | <cell biology, molecular biology> Intracellular membrane-associated proteins activated by several (e.g., beta adrenergic) receptors. They serve as second messengers or transducers of the receptor-initiated response to intracellular elements such as enzymes to initiate an effect. They are also mediators of activated cell-surface receptors and their enzymes or of ion channels. They are responsible for activating a chain of events that alters the concentration of intracellular signaling molecules such as cyclic AMP and calcium. In turn, these intracellular messengers alter the behaviour of other target proteins within the cell. These proteins have a high affinity for guanine nucleotides and hence are named "G" proteins. Synonym: G-protein, GTP-binding proteins. (12 Jul 2000) |

| G-protein coupled receptor | <cell biology> Cell surface receptors that are coupled to G-proteins (GTP-binding protein). G-protein coupled receptors are thought to have seven membrane spanning domains and have been divided into 2 subclasses: those in which the binding site is in the extracellular domain for example receptors for glycoprotein hormones, such as thyroid stimulating hormone (TSH) and follicle-stimulating hormone (FSH) and those in which the ligand binding site is likely to be in the plane of the 7 transmembrane domains for example rhodopsin and receptors for small neurotransmitters and hormones for example muscarinic acetylcholine receptor.
