Genome layout:


The deduced polyprotein has a length of 2,352 amino acids. There is a L protein with unknown function. 1AB remains uncleaved. 2A protein has a H-box/NC sequence motif.


See discussion under family description.


Viral RNA was detected in faeces of apparently healthy cats. Partial sakobu-like sequences were obtained from faecal samples of fur seals (Kluge et al., 2016).
