Abstract

The DNA-binding domains of eucaryotic GATA factors comprise a four-cysteine Zn finger and an adjacent basic region. Fungal GATA factors regulate nitrogen metabolism, light induction, siderophore biosynthesis and mating-type switching. Hydrophobic interactions determine binding-site specificity. Interactions with other factors may determine promoter specificity. One GATA factor has recently been shown to determine a drastic chromatin rearrangement.
