Family: Picornaviridae

Genus: Sakobuvirus



Distinguishing features

The genus is distinguished on the basis of genetic characters. 



No details are available on the morphology of virions. 

Nucleic acid

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

Genome layout:


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
