Enhancer trap construct that encodes a GAL4 driver. Generated in vivo by replacing the P{A92} element in the P{A92}puc^E69 insertion with sequence from a P{GawB} donor element. The replacement was not precise, resulting in the loss of both the ry^+t7.2 marker and lacZ reporter from the P{A92} insertion and the loss of the w^+mW.hs marker that is normally present in the P{GawB} element.
