The RMCE cassette of the Mi{MIC}CCAP-RMI05804 insertion has been replaced with a Trojan p65AD cassette that contains a splice acceptor site followed by the T2A peptide and sequence encoding a p65(AD)::Zip+ hemidriver (component of the 'Split GAL4' system, contains the transcriptional activation domain from the Homo sapiens 'p65' gene).
