| cystic fibrosis transmembrane conductance regulator | Gene believed to be defective in cystic fibrosis. Gene encodes a chloride channel, homologous to a family of proteins that actively transport small solutes in an ATP dependent manner (ABC transporters). The regulator protein is a protein which is embedded in the cell membrane and acts as a channel for certain ions to be transported into or out of the cell. The disease cystic fibrosis is caused by a defect in the gene for this protein. (09 Oct 1997) |

| hepatoma transmembrane kinase | <enzyme> A transmembrane tyrosine kinase of the eph subfamily; genbank u07695 Registry number: EC 2.7.1.- Synonym: htk protein, htk gene product (26 Jun 1999) |
| transmembrane | Through or across a membrane. (05 Mar 2000) |
| transmembrane potential | <physiology> More correctly, transmembrane potential difference: the electrical potential difference across a plasma membrane. See: resting potential, action potential. (18 Nov 1997) |
| transmembrane protein | <cell biology> A protein subunit in which the polypeptide chain is exposed on both sides of the membrane. The term does not apply when different subunits of protein complex are exposed at opposite surfaces. most integral membrane proteins are also transmembrane proteins. (13 Nov 1997) |
| transmembrane transducer | A system that transmits a chemical or electrical signal across a membrane. Usually involves a transmembrane receptor protein that is thought to undergo a conformation change that is expressed on the inner surface of the membrane. Many such transducing species are dimeric and the conformation change may involve interaction between the two components. (18 Nov 1997) |
| active transport | <biochemistry, chemistry> Transport of ions, nutrients or other molecules into a cell against a concentration gradient, this requires the expenditure of energy through ATP hydrolysis. (06 May 1997) |
| anterograde transport | Movement of material from the cell body of a neuron into axons and dendrites retrograde axoplasmic transport also occurs). (18 Nov 1997) |
| atrial transport function | The role of the atria in filling and stretching the ventricles by their presystolic contraction, without which the force of ventricular contraction and hence the cardiac output may significantly decrease. (05 Mar 2000) |
| axonal transport | Directed transport of organelles and molecules along a nerve cell axon. Transport can be anterograde (from the cell body) or retrograde (toward the cell body). (alberts et al., molecular biology of the cell, 3d ed, pg3) (12 Dec 1998) |
| axoplasmic transport | Transport by way of flow of axoplasm toward cell soma (retrograde) or toward axon terminal (anterograde). (05 Mar 2000) |
| biological transport | The movement of materials (including biochemical substances and drugs) across cell membranes and epithelial layers, usually by passive diffusion. (12 Dec 1998) |
| biological transport, active | The movement of materials across cell membranes and epithelial layers against an electrochemical gradient, requiring the expenditure of metabolic energy. (12 Dec 1998) |
| vectorial transport | <physiology> Transport of an ion or molecule across an epithelium in a certain direction (e.g. absorption of glucose by the gut). Vectorial transport implies a nonuniform distribution of transport proteins on the plasma membranes of two faces of the epithelium. (06 Mar 2000) |
| paracellular transport | Solvent movement across an epithelial cell layer through the tight junctions between cells. Compare: transcellular transport. (05 Mar 2000) |
