Structural highlights
Function
HAP1_YEASX Regulation of oxygen dependent gene expression. It modulates the expression of Iso-1 (CYP1) and Iso-2 (CYP3) cytochrome c. In response to heme, promotes transcription of genes encoding functions required for respiration, controlling oxidative damage and repression of anaerobic genes. Binds to the sequence 5'-CGGNNNTNNCGG-3'. Is non-functional in terms of iso-1 cytochrome c expression in strain S288c and its derivatives.[1] [2] [3] [4]
