RFY231 - MATalpha trp1::hisG his3 ura3-1 leu2::3Lexop-LEU2. This strain is used for two-hybrid assays, screens, and interaction mating assays. In the mating assay it is usually transformed with a TRP1 "prey" plasmid expresssing an activation domain (AD) fusion and mated to an RFY206 "bait" strain. Kolonin and Finley, 1998. Proc. Natl. Acad. Sci. USA 95, 14266-14271. [PNAS
RFY206 - Mata his3A200 leu2-3 lys2A201 ura3-52 trplA::hisG. This strain is used for yeast two-hybrid interaction mating assays. It can be transformed with the HIS3 "bait" plasmid (expressing a LexA fusion) and the URA3 reporter plasmid, then mated with RFY231 continaing the TRP1 "prey" plasmid (expressing an activation domain fusion).

Sci. U.S.A. 91:12980-12984. [Medline
Y306 - RFY206 contianing the URA3 lacZ reporter plasmid pSH18-34 made by Steve Hanes. pSH18-34 contains a GAL1-lacZ fusion with upstream LexA binding sites (operators).
