| receptors, complement 3d | Molecular sites on or in B-lymphocytes, follicular dendritic cells, lymphoid cells, and epithelial cells that recognise and combine with complement 3d. Human cr2 serves as a receptor for both c3dg and the gp350/220 glycoprotein of herpes virus 4, human, and binds the monoclonal antibody okb7, which blocks binding of both ligands to the receptor. (12 Dec 1998) |
|---|---|
| receptors, concanavalin a | Glycoprotein moieties on the surfaces of cell membranes that bind concanavalin a selectively; the number and location of the sites depends on the type and condition of the cell. (12 Dec 1998) |
| receptors, corticotropin | Cell surface receptors that bind corticotropin (acth, adrenocorticotropic hormone) with high affinity and trigger intracellular changes. Pharmacology suggests there may be multiple acth receptors. An acth receptor has been cloned and belongs to a subfamily of g-protein-coupled receptors. In addition to the adrenal cortex, acth receptors are found in the brain and immune systems. (12 Dec 1998) |
| receptors, corticotropin-releasing hormone | Cell surface proteins that bind corticotropin-releasing hormone with high affinity and trigger intracellular changes which influence the behaviour of cells. The corticotropin releasing-hormone receptors on anterior pituitary cells mediate the stimulation of corticotropin release by hypothalamic corticotropin releasing factor. The physiological consequence of activating corticotropin-releasing hormone receptors on central neurons is not well understood. (12 Dec 1998) |
| receptors, cxcr4 | Seven-transmembrane G-protein-coupled receptors for alpha-chemokines. They also function as fusion cofactors for T-cell-tropic HIV-1 strains. (12 Dec 1998) |
| receptors, cyclic AMP | Cell surface proteins that bind cyclic AMP with high affinity and trigger intracellular changes which influence the behaviour of cells. The best characterised cyclic AMP receptors are those of the slime mold dictyostelium discoideum. The transcription regulator cyclic AMP receptor protein of prokaryotes is not included nor are the eukaryotic cytoplasmic cyclic AMP receptor proteins which are the regulatory subunits of cyclic AMP-dependent protein kinases. (12 Dec 1998) |
| receptors, cytoadhesin | A group of integrins that includes the platelet outer membrane glycoprotein gpiib-iiia (platelet glycoprotein gpiib-iiia complex) and the vitronectin receptor (receptors, vitronectin). They play a major role in cell adhesion and serve as receptors for fibronectin, von willebrand factor, and vitronectin. (12 Dec 1998) |
| receptors, cytokine | Cell surface proteins that bind cytokines and trigger intracellular changes influencing the behaviour of cells. (12 Dec 1998) |
| receptors, cytoplasmic and nuclear | Proteins in the cytoplasm or nucleus that specifically bind signalling molecules and trigger changes which influence the behaviour of cells. The major groups are the steroid hormone receptors, which usually are found in the cytoplasm, and the thyroid hormone receptors, which usually are found in the nucleus. Receptors, unlike enzymes, generally do not catalyze chemical changes in their ligands. (12 Dec 1998) |
| receptors, dopamine | Cell-surface proteins that bind dopamine with high affinity and trigger intracellular changes influencing the behaviour of cells. (12 Dec 1998) |
| receptors, dopamine d1 | A class of dopamine receptors identified by their binding profiles for synthetic ligands, their molecular biology, and, perhaps, by their mode of action. (12 Dec 1998) |
| receptors, dopamine d2 | A class of dopamine receptors identified by their binding profiles for synthetic ligands, their molecular biology, and, perhaps, their mode of action. (12 Dec 1998) |
| receptors, drug | Proteins that bind specific drugs with high affinity and trigger intracellular changes influencing the behaviour of cells. Drug receptors are generally thought to be receptors for some endogenous substance not otherwise specified. (12 Dec 1998) |
| receptors, eicosanoid | Cell surface proteins that bind eicosanoids with high affinity and trigger intracellular changes influencing the behaviour of cells. Among the eicosanoid receptors are receptors for the prostaglandins, thromboxanes, and leukotrienes. (12 Dec 1998) |
| receptors, endothelin | Cell surface proteins that bind endothelin with high affinity and trigger intracellular changes which influence the behaviour of cells. (12 Dec 1998) |
