Element:Ulysses

Description Ulysses is a LTR retrotransposon characterized in the genome of Drosophila virilis (Scheinker et al. 1990). This element belongs to Osvaldo clade (Malik and Eickbush 1999). The genomic structure of Ulysses is 10.6 Kb in size including LTRs of 2.1 Kb. The internal region displays a Primer Binding Site (PBS) complementary to a tRNAHis, two Open Reading Frames (ORFs) for gag and pol genes, and a Polypurine Tract (PPT) adjacent to the 3´LTR (Scheinker et al. 1990; Evgen'ev, Corces, and Lankenau 1992). 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. (Craig et al. 2002)
