Effector. Definition. noun, plural: effectors. (biochemistry) A molecule that binds to a protein and affects the function of that protein. (physiology) An organ, a gland, or a muscle that can respond and becomes active in response to a stimulus (e.g. nerve impulse).upplement. In biochemistry, an effector is that molecule that binds to a specific protein, and regulates the latter's biological activity. An effector molecule acts as a ligand that is capable of increasing or decreasing the activity of that protein.
Effector response is the phenomenon that occurs after the immune system recognizes a foreign organism. A variety of cells and molecules are then recruited to mount an appropri â¦ ate response to eliminate or neutralize the organism.uch allosteric effectors are not covalently attached to the protein. Here, the activity of a protein is positively regulated by the binding of a factor. This factor could be a small molecule or another protein. What is important is that the allosteric binding site is distinct from the enzyme's catalytic site.
