Article

A yeast protein with homology to the beta-subunit of G proteins is involved in control of heme-regulated and catabolite-repressed genes.

Gene - 15 Jan 1991

Abstract excerpt

The product of the Saccharomyces cerevisiae AER2 gene is responsible for maintaining repression of at least two distinct regulatory pathways: heme activation/repression and catabolite repression. Mutations in the gene caused an eightfold increase in the expression of the heme-activated CYC1 gene in the absence of heme, a substantial increase in the expression of the heme-repressed ANB1 gene in the presence of...
