A set of transgenic insertion stocks containing a protein trap cassette, derived from Mi{MIC} insertions in coding introns using Recombinase-Mediated Cassette Exchange (RMCE); see http://flypush.imgen.bcm.tmc.edu/pscreen/technique.html. The protein trap cassette contains a EGFP-FlAsH-StrepII-TEV-3xFlag ("GFSTF") tag that is flanked on either side with a 4X(GlyGlySer) flexible linker; the mini-yellow marker is no longer present. Each insertion line contains one of three versions of the cassette (Mi{PT-GFSTF.0}, Mi{PT-GFSTF.1} or Mi{PT-GFSTF.2}), depending on the reading frame required to generate an in-frame fusion protein with the gene in which the insertion is located. This system also allows UAS/GAL4-based knockdown strategies targeting GFP-sequence containing mRNA (RNAi against GFP) or GFP fusion protein (deGradFP).
MI00296-GFSTF.0
The attP cassette of the Mi{MIC} element has been replaced with the attB protein-trap cassette from the pBS-KS-attB1-2-PT-SA-SD-0-EGFP-FlAsH-StrepII-TEV-3xFlag plasmid by phiC31-mediated recombination. The attB protein-trap cassette contains a multi-tag cassette consisting of the EGFP version of Avic\GFP, T:Zzzz\TC, T:Zzzz\StrepII, T:Zzzz\TEV.CS and 3xT:Zzzz\FLAG.
