From The Gypsy Database

Description

Xanthias is a LTR retrotransposon described in the genome of Drosophila melanogaster (GenBank accession FJ238509). This Ty1/Copia-like LTR retrotransposon belongs to 1731 clade within Branch 2 of the Ty1/Copia family (Llorens et al. 2009). The genome of Xanthias is 4533 bp in size, including LTRs of 206 nt. The LTRs flanked internal region encodes for a single long ORF showing the typical gag-pol domains structure of Ty1/Copia LTR retrotransposons (gag, protease, integrase, reverse transcriptase and ribonuclease H).

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
