| Standard Name | Hap1p |
|---|---|
| Systematic Name | Ylr256wp |
| Alias | Cyp1p 1 |
| ORF Classification | Verified |
| Description | Zinc finger transcription factor involved in the complex regulation of gene expression in response to levels of heme and oxygen; the S288C sequence differs from other strain backgrounds due to a Ty1 insertion in the carboxy terminus (2, 3, 4, 5, 6) |
| Name Description | Heme Activator Protein 3, 7 |
