|description=''Tse3'' is a LTR retrotransposon characterized in ''Saccharomyces exiguus'' ([[Literature:54327|Neuveglise et al.2002]]). ''Tse3'' belongs to the ''Chromoviridae'' branch, term suggested ([[Literature:47259|Marín and Lloréns 2000]]) to describe the ''Ty3/Gypsy'' elements bearing chromodomain-integrases ([[Literature:46552|Malik and Eickbush 1999]]). The chromovirus branch has been disclosed to be the most ancient phylogenetic pattern of ''Ty3/Gypsy'' retroelements ([[Literature:26737|Gorinsek, Gubensek and Kordis 2004]]; [[Literature:26736| 2005]]; [[Literature:39523|Kordis 2005]]).

The genomic structure of ''Tse3'' is 6.5 Kb in size, including LTRs of 947-948 nt. The internal region displays a Primer Binding Site (PBS), two Open Reading Frames (ORFs) the ''gag'', and ''pol'' genes, and a Polypurine Tract (PPT) adjacent to the 3´LTR ([[Literature:54327|Neuveglise et al.2002]]). Apparently, ''Tse3'' does not bear chromodomain at the C-terminal end of its integrase domain. The PBS of fungi and vertebrate chromoviruses, differs significantly from that used by plant chromoviruses. While plant chromoviruses use a methionine starting tRNA (iMet), fungi and vertebrate chromoviruses use their own self-priming mechanism to start the reverse transcription ([[Literature:43217|Levin 1995 ]]; [[Literature:10125|Butler et al. 2001]]).
