Element:Tor1

Description

Tor1 is a Ty3/Gypsy lineage of LTR retrotransposons described, together with three other Ty3/Gypsy lineages and other retrotransposons, in the miniature genome of the tunicate Oikopleura dioica (Volff et al. 2004). The genome of Tor1 is 7.8 Kb in size (including two LTRs no described here with no apparent homology each other). The internal region of this element contains a Primer Binding Site (PBS), coding region and Polypurine Tract (PPT). The coding region displays two overlapped ORFs encoding for the gag and pol domains typical of LTR retrotransposons (Volff et al. 2004).

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
