effector

 [ef-fek´ter]
1. an agent that mediates a specific effect, as an allosteric effector or an effector cell.
2. an organ that produces an effect, such as contraction or secretion, in response to nerve stimulation; see also receptor.
allosteric effector one that binds to an enzyme at a site other than the active site.

ef·fec·tor

(ē-fek'tŏr, -tōr),
1. As defined by Sherrington, a peripheral tissue that receives nerve impulses and reacts by muscular contractioon, glandular secretion, or electric discharge (from an electric organ, as in the case of certain bony fishes such as the electric eel).
2. A small metabolic molecule that, by combining with a repressor gene, depresses the activity of an operon.
3. A small molecule that binds to a protein or other macromolecule and, in so doing, alters the activity of that macromolecule.
4. An individual or a substance, technique, procedure, or person causing an effect.

effector

/ef·fec·tor/ (ĕ-fek´ter)
1. an agent that mediates a specific effect.
2. an organ that produces an effect in response to nerve stimulation.

allosteric effector  an enzyme inhibitor or activator that has its effect at a site other than the catalytic site of the enzyme.

effector

(ĭ-fĕk′tər)
n.
1. A muscle, gland, or organ capable of responding to a stimulus, especially a nerve impulse.
2. A nerve ending that carries impulses to a muscle, gland, or organ and activates muscle contraction or glandular secretion.
3. Biochemistry A small molecule or protein that alters biochemical processes in a cell, as by decreasing or increasing the activity of an enzyme.

effector

[ifek′tər]
Etymology: L, efficere, to accomplish
1 an organ that produces an effect, such as glandular secretion, as a result of nerve stimulation.
2 a molecule, such as an enzyme, that can start or stop a chemical reaction.

effector

An organ, such as a gland or muscle, that responds to a motor stimulation. See Allosteric effector.

ef·fec·tor

(e-fek'tŏr)
1. A peripheral tissue that receives nerve impulses and reacts by contraction (muscle), secretion (gland), or a discharge of electricity (electric organ of certain bony fishes).
2. A small metabolic molecule that, by combining with a repressor gene, depresses the activity of an operon.
3. A small molecule that binds to a protein and, in so doing, alters the activity of that protein.
4. A substance, technique, procedure, or individual that causes an effect.

effector

a structure or organ that brings about an action of'effect’ as a result of a stimulus received through a RECEPTOR which can come from the CNS or from a hormone. The effector is usually a muscle but can be a gland.

effector (ēfek´tur),

n 1. a motor or secretory nerve ending in an organ, gland, or muscle; consequently called an
effector organ. n 2. an on-the-job organ of the body that responds to stimulations asking for corrections. Antonym: receptor.

effector

1. a muscle or gland that contracts or secretes, respectively, in direct response to nerve impulses.
2. a molecule that binds to an enzyme with an effect on its catalytic activity, i.e. either an activator or inhibitor.

allosteric effector
one that binds to an enzyme at a site other than the active site.
effector cell
cell in the immune system that mediates an immune function.
