The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
Genome (Ng et al., 2014): c. 7,800 nt (5′-UTR: 591 nt; ORF: 7,059 nt; 3′-UTR: 157 nt). The 5′-UTR contains a predicted type IV IRES. The location of the cre has not been identified.
Genome organization and replication
The deduced polyprotein is of 2,352 amino acids. There is an L protein with unknown function. 1AB remains uncleaved. The 2A protein has an H-box/NC sequence motif.
No virus has been isolated. Viral RNA was detected in faeces of apparently healthy cats. Partial sequences of sakobu-like viruses were obtained from faecal samples of fur seals (Kluge et al., 2016).
Derivation of names
Sakobuvirus: from salivirus- and kobuvirus-related virus
