Mi{2A-d2GFP-NLS.1} represents a transgenic construct generated in vivo by using phiC31:int-mediated recombination to replace the attP cassette of a Mi{MIC} element insertion with an intron phase 1 'Trojan' sequence cassette that consists of a splice acceptor site followed by: the T2A peptide - a destabilized form of GFP tagged with a nuclear localization signal - an Hsp70 transcription termination signal.
