Probable acetyltransferase that binds the 5'-GGACTACAG-3' sequence of coproporphyrinogen oxidase promoter. Able to activate transcription of a reporter construct in vitro (By similarity). Probable acetyltransferase. May act as a transcription factor regulating the expression of coproporphyrinogen oxidase by binding to a promoter regulatory element. Belongs to the camello family.
