''Xen 1'' belongs to genus ''Epsilonretrovirus'' within ''Retroviridae'' family (''International Committee on the Taxonomy of Viruses'' -ICTV- [[Literature:100589|Fauquet ''et al''. 2005]]) and according to [[Literature:100596|Llorens ''et al''. 2009]] is located within Class 1 of the [[Retroviridae|''Retroviridae'']] family.<br /> <br /> The genome of ''Xen 1'' is 10.2 Kb, including 5' and 3' LTRs of 550 and 548 bp in length, respectively, ([[Literature:35936|Kambol ''et al.'' 2003]]). The internal region of this element displays a Primer Binding Site (PBS) complementary to a tRNA&lt;sup&gt;Lys2&lt;/sup&gt;, seven Open Reading Frames (ORFs) that code for two accessory ORFs, gag, pol (PR-RT-RNase H-INT) polyprotein domains, and a Polypurine Tract (PPT) adjacent to the 3&amp;acute;LTR ([[Literature:35936|Kambol ''et al.'' 2003]]).<br /> |structure=XEN1.png<br /> |host=Xenopus laevis<br /> |hostpic=Xenopus.jpg<br /> |literature=*[[Literature:14014|Retroviruses.
