|description=''Sushi-ichi'' is a LTR retrotransposon characterized in ''Takifugu rubripes'' ([[Literature:60737|Poulter and Butler 1998]]; [[Literature:10125|Butler et al. 2001]]; [[Literature:80623|Volff et al. 2003]]). ''Sushi'' belongs to ''V-clade'' ([[Literature:100596|Llorens et al. 2009]]) the chromovirus lineage of vertebrate-like ''Ty3/Gypsy'' LTR retrotransposons ([[Literature:47259|Marín and Lloréns 2000]]) characterized by encoding for 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]]).

''Sushi ''has several subtypes. ''Sushi-ichi'' is taken as representative. Its genome is 5.6 Kb in size, including LTRs of 560 nt. The internal region of this element displays a Primer Binding Site (PBS), two Open Reading Frames (ORFs) for ''gag'', and ''pol'' genes, and a Polypurine Tract (PPT) adjacent to the 3´LTR ([[Literature:60737|Poulter and Butler 1998]]; [[Literature:10125|Butler et al. 2001]]; [[Literature:80623|Volff et al. 2003]]). This element presents a detectable chromodomain at the C-terminal end of the integrase pol polyprotein 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]]).
