Description

Zeco2 is a Ty1/Copia-like LTR retrotransposon described, together its closer related element Zeco1, in the genome of the zebrafish (Danio rerio) (Terrat et al. 2008). It belongs to GalEA clade a Ty1/Copia lineage specifically found in marin animals (Terrat et al. 2008).

The genome of Zeco2 is about of 4.8 Kb in size (4840 bp long) including a 204-bp 5’ LTR and a 197-bp 3’LTR that flank an internal coding region. Although this region is disrupted by a several stop codons and frameshifts, it displays the typical gag and pol domains associated to Ty1/Copia LTR retrotransposons. A Primer Binding Site (PBS) complementary to a tRNAMet and a Polypurine Tract (PPT) are located respectively downstream and upstream to the 5’LTR and 3’LTR (Terrat et al. 2008).

MA=matrix PR=protease DU or DUT=dUTPase TM=transmembrane TAV or IBMP=transactivator/viroplasmin or inclusion body matrix protein
CA=capsid RT=reverse transcriptase INT=Integrase CHR=chromodomain
NC=nucleocapsid RH=RNaseH SU=surface MOV=movement protein
PPT=polypurine tract PBS=primer binding site ATF=aphid transmission factor VAP=virion associated protein
