| glycine receptor | <physiology> Chloride channel forming receptor. One of a family of neurotransmitter receptors with fast intrinsic ion channels. See: amino acid receptors. (18 Nov 1997) |
|---|---|
| peptide receptor | Specific receptor for peptide neurotransmitters. (18 Nov 1997) |
| 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.

| chemokine receptor | A molecule that receives a chemokine and a chemokine dock. Several chemokine receptors are essential co-receptors for HIV. (12 Dec 1998) |
| metabotropic receptor | A type of receptor that is linked to intracellular production of 1,2-diacylglycerol and inositol 1,4,5-trisphosphate. Origin: metabolism + G. Trope, turning, inclination, + -ic (05 Mar 2000) |
| ryanodine receptor calcium release channel | Protein complexes that mediate the release of calcium from the sarcoplasmic reticulum in both skeletal and cardiac muscle cells by forming tetrametric complexes. These complexes each then act as a calcium channel. There are three isoforms of the ryr: ryr1, ryr2, and ryr3. Ryr1 is specifically expressed in skeletal muscles and ryr2 in cardiac muscles. Ryr3 is yet another isoform found in non-muscle cells such as neuronal cells. (12 Dec 1998) |
| PL7a receptor-tyrosine kinase | <enzyme> A member of the eph receptor tyrosine kinase subfamily; shows 80% identity with myk-1; genbank l43622 Registry number: EC 2.7.1.- Synonym: pl7a protein (26 Jun 1999) |
| Con A receptor | <biochemistry> A common misuse of the term receptor. Con A binds to the mannose residues of many different glycoproteins and glycolipids and the binding is therefore not to a specific site. It could be argued that the receptor is the Con A and cells have Con A ligands on their surfaces: certainly this would be less confusing. (05 Jan 1998) |
| muscarinic acetylcholine receptor | Distinct from the nicotinic ACh receptor in having no intrinsic ion channel, the receptor is formed from one protein chain with 7 transmembrane regions. The receptors produce their effect via activation of GTP-binding proteins. (18 Nov 1997) |
| muscarinic receptor kinase | <enzyme> Phosphorylates muscarinic acetylcholine receptors and beta-adrenergic receptors Registry number: EC 2.7.- Synonym: muscarinic acetylcholine receptor kinase, machr kinase (26 Jun 1999) |
| cyclic AMP receptor protein | A transcriptional regulator in prokaryotes which, when activated by binding cyclic AMP, acts at several promoters. Cyclic AMP receptor protein was originally identified as a catabolite gene activator protein. It was subsequently shown to regulate several functions unrelated to catabolism, and to be both a negative and a positive regulator of transcription. Cell surface cyclic AMP receptors are not included (cyclic AMP receptors), nor are the eukaryotic cytoplasmic cyclic AMP receptor proteins, which are the regulatory subunits of cyclic AMP-dependent protein kinases. (12 Dec 1998) |
| presynaptic receptor | <physiology> Receptors located on presynaptic terminals at synapses. (05 Mar 1998) |
| progesterone receptor assay | The progesterone receptor test (PgR assay) checks the tumour for its hormone status. (16 Dec 1997) |
| Xiphophorus melanoma receptor kinase | <enzyme> Growth factor receptor protein with an extracellular ligand binding domain and an intracellular catalytic domain Registry number: EC 2.7.1.- Synonym: xmrk protein (26 Jun 1999) |
| selective oestrogen-receptor modulator | <pharmacology> An antioestrogen which possesses some, but not all, of the actions of oestrogen. For example, raloxifene (evista) is classified as a SERM because it prevents bone loss (like oestrogen) and lowers serum cholesterol (like oestrogen) but (unlike oestrogen) does not stimulate the endometrial lining of the uterus.
