Retrotransposon Gag like family
retrotransposon gag like family
The genes of this family have undergone major structural and functional changes that benefit their hosts during a process called domestication, generating new genes or regulatory factors and contributing to evolutionary diversity. The SIRH family alias derives from the resemblance of the genes to the sushi-ichi-related retrotransposon, but the genes are derived from an extinct retrovirus. The human genes were identified from a search for GAG homologs in the human genome.
