The R82F12 enhancer fragment is fused upstream of the Drosophila synthetic core promoter (DSCP) followed by the p65(AD)::Zip+ hemidriver (component of a 'split driver' system, contains the p65 activation domain). A Hsp70 transcriptional terminator is present.

Silencing of L2 lamina output neurons, using Hsap\RELAAD.R82F12.T:Zzzz\Zip+, Scer\GAL4DBD.R75H08.T:Zzzz\Zip- and Hsap\KCNJ2Scer\UAS.T:Avic\GFP-EGFP, significantly affects fly responses to many different visual behavioural conditions.
