Family: Coronaviridae

Subfamily: Pitovirinae

Distinguishing features

The subfamily Pitovirinae was established for the virus Pacific salmon nidovirus based on its low overall genome sequence identity with other coronaviruses despite conservation of the canonical replicase domains found in other members of the family Coronaviridae (Figure 1.Pitovirinae).

ORFs are depicted as coloured boxes with skyblue, lamina-associated polypeptide 1C (LAP1C); red, S; cyan, E; yellow, M and magenta, N. ORFs for accessory proteins are depicted as coloured boxes in grey.
