Genus

Genus: Triatovirus

Family: Dicistroviridae

Genus: Triatovirus

 

Distinguishing features

Cricket paralysis virus, Israeli acute paralysis virus, and triatoma virus possess a conserved ternary motif (Asp-Asp-Phe) thought to catalyze the cleavage of VP0 into VP3 and VP4. In triatoma virus, a second identical triad exposed to the capsid interior is present in VP3. This motif is conserved in black queen cell virus, Himetobi P virus, and Plautia stali intestine virus. 

Genus

Genus: Cripavirus

Family: Dicistroviridae

Genus: Cripavirus

 

Distinguishing features

Members of the Cripavirus genus exhibit the Type I intergenic untranslated region (IGR) internal ribosome entry site (IRES) structure (Jan et al. 2006).  The type I IRES is characterized by the presence of a conserved consensus bulge sequence (UGAUCU/UGC), absence of a third stem loop in Pseudoknot I, and the presence of a consensus sequence (UUAC) downstream of stem loop I.
