Genome organization and replication

Genome layout:

VPg+5'UTR^IRES-I[1A-1B-1C-1D/2A-2B-2C/3A-3B-3C-3D]3'UTR-poly(A)

The deduced polyprotein has a length of 2,420 amino acids. There is no L protein. The function 2A is unknown. 

Antigenicity

See discussion under family description.

Biology

Viral RNA was detected in faeces of a 5-week-old common kestrel (Falco tinnunculus).

Species demarcation criteria

Not applicable

Member species

Virus names, the choice of exemplar isolates, and virus abbreviations, are not official ICTV designations.

Derivation of names

Harka: from Harkakötöny (a village in Hungary where the first sample was collected)
