Virus classification
Group: Group VI (ssRNA-RT)
Family: Metaviridae


Metaviridae are a family of reverse transcriptase, integrase, and capsid proteins. The reverse transcriptase and integrase proteins are needed for the retrotransposon activity of the virus. In some cases, virus-like particles can be formed from capsid proteins.

Some assembled Metaviridae particles can penetrate and infect previously uninfected cells. An example of this is the gypsy, a retroelement found in the Drosophila melanogaster genome. The ability to infect other cells in determined by the presence of the retroviral env genes which encode coat proteins.


Metaviridae are split into the following genera:
