Induction of [URE3] by compositionally similar domains. (A) Amino acid sequences of the tested domains. The locations of the segments within the respective protein sequences is indicated. (B) Yeast strain YER135 expressing wild-type URE2 was transformed with either a plasmid containing the GAL1 promoter (vector) or expressing the indicated PFD from the GAL1 promoter. USA selection was conducted as in Figure 1A. (C) Western blots of the compositionally similar fragments. PFDs were HA tagged and detected as in Figure 1B.
