This protein is a positive regulator for the gene expression of the galactose-induced genes such as GAL1, GAL2, GAL7, GAL10, and MEL1 which code for the enzymes used to convert galactose to glucose. It recognizes a 17 base pair sequence in (5-CGGRNNRCYNYNCNCCG-3) the upstream activating sequence (UAS-G) of these genes.
