Qinviridae (taxid:2501968)

VIRION

Unknown, discovered using viral metagenomics.

GENOME

Segmented Negative-stranded RNA linear genome: RNA1 segment is about 6 kb, RNA2 segment about 1.6 kb.
Encodes for two proteins.

GENE EXPRESSION

Viral RNA-dependent RNA polymerase (L) binds to a promoter on each segment and transcribes a messenger RNA.

ENZYMES

• RNA-dependent RNA polymerase L
• Mononega-type capping
  • RNA TPase, GTase, N7 Mtase, 2'O Mtase L

REPLICATION

NUCLEAR or CYTOPLASMIC?

1. Virus invades host cells by unknown mechanism: genomic segments are released in cytoplasm.
2. Transcription
3. Replication
4. Unknown mechanism of propagation.
