Design Notes
We get this 452bp sequence from FlyBase ( Dmel\ple [http://flybase.org/reports/FBgn0005626.html]). We regard the 5'-UTR region as promoter region of ple.
This should not be the most accurate and concise promoter sequence. We hope that subsequent users will be able to accurately identify the promoter sequence.
We combined this promoter with UAS/GAL4 system to achieve gene expression in specific cells. (More details [http://2017.igem.org/Team:Tongji_China/Design])
We cloned this 452bp TH promoter easily from D. melanogaster 's genomic DNA and the sequencing result is correct.
We connected TH promoter to GAL4( BBa_K2374004 [1] )and GAL80ts( BBa_K2374002 [2] )respectively, and cloned them into pUAST vector which had been removed the UAS sequence( BBa_K2374008 [3] ), then to microinject them into Drosophila 's eggs. After hybridization screening, we got stable modified fruit fly strains. Finally, we did RT-PCR, qPCR and behavioral experiments to test our system.
We cloned TH promoter into pSB1C3 for submission. Here shows the 1% Agarose gel electrophoresis image.
We did 2 mutagenesis on this sequence.
site direct mutagenesis:
1. EcoR I (184) GAATTC->GATTTC
2. Xba I (219) TCTAGA->TGTAGA
