Subject: Re: FlyBase Query (cy1375)
The BamHI site was introduced in ccgcaggaTccaaatccc, 64bp
downstream of the tatabox of YP1. So it's an YP1 promoter fusion.

>Hi Chihiro,
Sorry for the delay, but you know how it is...The Gal4 line
was constructed here.
A BamHI site was introduced 64bp downstream of the tatabox of the YP1
gene (LOCUS DMYOLK1 1677 bp DNA INV
07-NOV-1997
DEFINITION Drosophila intergenic spacer and exon 1 from YPI and YPII gene for
yolk protein. ACCESSION X01524 M11170, prom Yolk-prot1). This
Hind3-BamHI(new) fg. was fused to BamHI site 5' of the Gal4 coding
region of pGATB (Brand & Perrimon) . The whole fusion was cloned into
pCasPer as an EcoRI-NotI 4192bp fg. and injected.
The sequence of the yolk casper vector is available. I can send it to
you or people can ask it from me.
The expression is fat body in female only which is what I was
looking for. By the way, I received a lot of requests for this line
and I'm still amplifying it before giving it away. I think that I
will send it to Bloomington.
Hope this helps...
Don't hesitate to contact me if needed..
Take care
Jean-Marc
