Endogenous Retroviruses in Fish Genomes: From Relics of Past Infections to Evolutionary Innovations?
The increasing availability of fish genome sequences has allowed to gain new insights into the diversity and host distribution of retroviruses in fish and other vertebrates. This distribution can be assessed through the identification and analysis of endogenous retroviruses, which are proviral remnants of past infections integrated in genomes. Retroviral sequences are probably important for evo...
متن کاملIdentification and Phylogenetic Analysis of Schizophrenia Associated Retrovirus (SZRV) Element in the Human GenBank Database
A significant proportion of the human genome consists of interspersed repetitive DNA sequences. One type of repetitive DNA elements is human endogenous retroviruses (HERVs), representing about 1% of the human genome. Their structures closely resemble those of retroviruses, and include internal sequences with homology to gag, pol, and env open reading frames (ORFs) flanked by long terminal repea...
متن کاملIn between: Gypsy in Drosophila melanogaster Reveals New Insights into Endogenous Retrovirus Evolution
Retroviruses are RNA viruses that are able to synthesize a DNA copy of their genome and insert it into a chromosome of the host cell. Sequencing of different eukaryote genomes has revealed the presence of many such endogenous retroviral sequences. The mechanisms by which these retroviral sequences have colonized the genome are still unknown, and the endogenous retrovirus gypsy of Drosophila mel...
متن کاملDiscovery of a Novel Retrovirus Sequence in an Australian Native Rodent (Melomys burtoni): A Putative Link between Gibbon Ape Leukemia Virus and Koala Retrovirus
Gibbon ape leukaemia virus (GALV) and koala retrovirus (KoRV) share a remarkably close sequence identity despite the fact that they occur in distantly related mammals on different continents. It has previously been suggested that infection of their respective hosts may have occurred as a result of a species jump from another, as yet unidentified vertebrate host. To investigate possible sources ...
متن کاملEvolution and characterization of tetraonine endogenous retrovirus: a new virus related to avian sarcoma and leukosis viruses.
In a previous study, we found avian sarcoma and leukosis virus (ASLV) gag genes in 19 species of birds in the order Galliformes including all grouse and ptarmigan (Tetraoninae) surveyed. Our data suggested that retroviruses had been transmitted horizontally among some host species. To further investigate these elements, we sequenced a replication-defective retrovirus, here named tetraonine endo...
