The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
Genome (S. Yang, Y. Wang, W. Zhang, unpublished): c. 7,443 nt (5′-UTR: 631 nt; ORF: 6,633 nt; 3′-UTR: 179 nt). The location of the cre has not been identified.
Genome organization and replication
The deduced polyprotein is of 2,211 amino acids. There is no L protein. 1A is very short (19 amino acids). The function of 2A is unknown.
No virus has been isolated. Viral RNA was detected in faeces of red-crowned cranes (Grus japonensis).
Derivation of names
Crahelivirus: derived from crane (host) and hepato-like
