Enveloped, bullet shaped. About 80 nm in diameter and 120 nm long.
Negative-stranded RNA linear genome, about 11 kb in size. Encodes for five to seven proteins, including the five canonical rhabdovirus structural proteins genes, plus additional open reading frames at various positions.
The viral RNA dependent RNA polymerase binds the encapsidated genome at the leader region, then sequentially transcribes each genes by recognizing start and stop signals flanking viral genes.
- Attachment of the viral G glycoproteins to host receptors mediates endocytosis of the virus into the host cell.
- Fusion of virus membrane with the vesicle membrane; ribonucleocapsid is released into the cytoplasm.
- Sequential transcription , viral mRNAs are capped and polyadenylated by polymerase stuttering in the cytoplasm.
- Replication presumably starts when enough nucleoprotein is present to encapsidate neo-synthetized antigenomes and genomes.
- The ribonucleocapsid binds to the matrix protein and buds, releasing new virions.
