Nucleic acid

Genome [{Zylberberg et al., 2016:27460795:3331RJOHTXZylberberg et al., 2016, Novel picornavirus associated with avian keratin disorder in Alaskan birds, MBio, 7, 4, }]: 7,653 nt (5′UTR: 788 nt; ORF: 6,780 nt; 3′UTR: 85 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:

VPg+5′-UTR-[1AB-1C-1D/2A-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of 2,260 aa. The genome encodes no L protein. 1AB remains uncleaved. The function of the 2A protein is unknown.

Antigenicity

See discussion under family description.

Biology

Viral RNA has been detected in tissue samples (mandible) of diseased black-capped chickadees (Poecile atricapillus) in Anchorage and the Matanuska-Sustna Valley, Alaska, USA. The virus is suspected to cause the avian keratin disorder (AKD).
