Length of genome (Woo et al., 2010): c. 7,640-7,678 nt (5'-UTR: 636-646 nt; ORF: 6,765-6,774 nt; 3' UTR: 238-256 nt). The location of the cre has not been identified.
The deduced polyprotein has a length of 2,255-2,258 aa. The genome encodes a L protein. 1AB remains uncleaved (with myristoylation signal). 2A protein has unknown function.
See discussion under family description.
Viral RNA was detected in faeces of the oriental magpie robin (Copsychus saularis) and the grey-backed thrush (Turdus hortulorum). Two genetic virus types are defined.
The single species Oscivirus A includes two genetic types classified by means of phylogenetic clustering.
Osci: from Oscines (Latin oscen, 'a songbird')
