Satellite viruses | |
A satellite is a subviral agent composed of nucleic acid that depends on the co-infection of a host cell with a helper or master virus for its replication. When a satellite encodes the coat protein in which its nucleic acid is encapsidated it is referred to as a satellite virus. A satellite virus of mamavirus that inhibits the replication of its host has been termed a virophage.[1] However, the usage of this term remains controversial due to the lack of fundamental differences between virophages and classical satellite viruses.[2]
The genomes of satellites range upward from 359 nucleotides in length for Satellite Tobacco Ringspot Virus RNA (STobRV).[3]
Satellite viral particles should not be confused with satellite DNA.
