CC -!- FUNCTION: Regulation of oxygen dependent gene expression. It modulates
CC the expression of Iso-1 (CYP1) and Iso-2 (CYP3) cytochrome c. In
CC response to heme, promotes transcription of genes encoding functions
CC required for respiration, controlling oxidative damage and repression
CC of anaerobic genes. Binds to the sequence 5'-CGGNNNTNNCGG-3' (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Binds DNA as a homodimer. Interacts with SRO9 and YDJ1. In the
CC absence of heme, binds to at least four cellular proteins, including
CC YDJ1 and SRO9, forming a high-molecular-weight complex (HMC) which
CC results in repression of its activity and dictates its DNA-binding
CC specificity (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00227}.
CC -!- MISCELLANEOUS: Heme is an effector molecule for CYP1/HAP1. The repeat
CC region (see FT table) mediates heme induction by masking the DNA-
CC binding domain in the absence of inducer (By similarity).
CC {ECO:0000250}.
