General Information
Term binary expression system - driver ID (Ontology) FBcv:0005059 (FlyBase CV)
Definition Transactivator ('driver') that is encoded by a transgenic locus or modified endogenous locus and which forms part of a binary expression system. This system requires a transactivator ('driver') that binds to a specific DNA sequence ('regulatory region' or 'effector'). A driver encoded by one transgenic locus or modified endogenous locus is used to drive expression of a downstream 'responder' or 'reporter' encoded by another transgenic locus or modified endogenous locus, by fusing the regulatory region sequence to which the driver binds upstream of the responder sequence. The temporal and spatial expression pattern of the responder thus depends on the regulatory elements used to drive expression of the driver. In addition, a specific repressor protein may be available which prevents the transactivator from driving expression, allowing further refinement of the expression pattern of the responder.[ FlyBase:FBrf0216478 ]
