Regions in the promoter of the yeast FBP1 gene implicated in catabolite repression may bind the product of the regulatory gene MIG1

FEBS Lett. 1991 Oct 7;291(1):97-100. doi: 10.1016/0014-5793(91)81112-l.

Abstract

We have identified in the promoter of the yeast FBP1 gene two sites able to bind nuclear proteins. These sites have a nucleotide sequence strongly similar to that of sites which bind the regulatory protein MIG1 in the promoters of GAL4 and SUC2. Deletions performed in the FBP1 promoter showed that one of the sites contributes to catabolite repression of this gene. In this same promoter, another region was identified with a strong effect on the catabolite repression of FBP1. In this region a sequence similar to the consensus for the binding site of the MIG1 protein was also present.
