Element:Zeco1

Description Zeco1, a Ty1/Copia-like LTR retrotransposon, is associated to the family of GalEa-like elements and has been described 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 Zeco1 is 4.8 Kb in size (4807 bp long) including two identical 192-bp LTRs. It presents a LTRs flanked internal coding region disrupted by a frameshift and several stop codons but displaying 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). Structure Figure not to scale. If present, long terminal repeats (LTRs) have been highlighted in blue. Amino acid motifs noted with lines indicate the conserved residues in each protein domain, abbreviations below mean: 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 Related literature Mobile DNA II.
