Genus: Etapapillomavirus

Genus: Etapapillomavirus

Distinguishing features

Members of this genus are associated with cutaneous lesions in birds. Unlike the prototypical E6 protein which contains two zinc-binding motifs, the etapapillomavirus E6 protein contains a single zinc-binding motif. These papillomaviruses contain an E9 protein of unknown function. No E8^E2 or E1^E4 proteins have been identified.
