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.
From Wikipedia, the free encyclopedia. Transcription activator-like effector nucleases (TALENs) are artificial restriction enzymes generated by fusing a TAL effector DNA-binding domain to a DNA cleavage domain. Restriction enzymes are enzymes that cut DNA strands at a specific sequence. Transcription activator-like effectors (TALEs) can be quickly engineered to bind practically any desired DNA sequence. By combining such an engineered TALE with a DNA cleavage domain (which cuts DNA strands), one can engineer restriction enzymes that are specific for any desired DNA sequence.
