Taxonomy
Table legend: "*" denotes type species.
Structure
Tupavirions enveloped, with bullet shaped geometries. These particles are about 160 nm long. Tupavirus genomes are linear, around 11.2 kb in length. The genome codes for 7 proteins.
Life Cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral G glycoproteins to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the negative stranded RNA virus replication model. Negative stranded RNA virus transcription, using polymerase stuttering is the method of transcription. The virus exits the host cell by budding, and tubule-guided viral movement. Birds serve as the natural host.
