| receptor protein | An intracellular protein (or protein fraction) that has a high specific affinity for binding a known stimulus to cellular activity, such as a steroid hormone or adenosine 3',5'-cyclic phosphate. (05 Mar 2000) |
|---|---|
| receptor protein-tyrosine kinase | <enzyme> A catalytic protein-tyrosine kinase domain found on the cytoplasmic beta-portion of receptors. Many growth and differentiation factor receptors contain this domain. It is critical for the signal transduction pathways required for mitogenesis, transformation, and cell differentiation. Registry number: EC 2.7.1.- (12 Dec 1998) |
| receptor site | Point of attachment of viruses, hormones, or other activators to cell membranes. (05 Mar 2000) |
| receptor tyrosine kinase | Class of membrane receptors that phosphorylate tyrosine residues. Many play significant roles in development or cell division. Examples: insulin receptor family, c ros receptor, Drosophila sevenless, trk family. (18 Nov 1997) |
| receptor, visual | The layer of rods and cones, the visual cells, of the retina. (12 Dec 1998) |
| Cek4 receptor protein-tyrosine kinase | <enzyme> Isolated from mouse and chicken. Registry number: EC 2.7.1.- Synonym: cek4 protein, cek4 eph receptor, eph receptor cek4 (26 Jun 1999) |
| visual receptor cells | The rod and cone cell's of the retina. (05 Mar 2000) |
| glutamate receptor | <physiology> See amino acid receptor superfamily. Glutamate receptors are implicated in many important brain functions including long-term potentiation (LTP). at least 4 major glutamate gated ion channel subtypes are presently distinguished on pharmacological grounds, named after their most selective agonists: N methyl D aspartate (NMDA implicated in memory and learning, neuronal cell death, ischaemia and epilepsy), kainic acid (KA), quisqualate/AMPA and L 2 amino 4 phosphobutyrate (APB). A fifth subtype (APCD) trans 1 amino cyclopentane 1,3 dicarboxylate is a G-protein coupled receptor. (18 Nov 1997) |
| 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. (18 Nov 1997) |
| 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) |
