Element:Zebel

From The Gypsy Database

Description

Zebel is a LTR retrotransposon found in the zebrafish Danio rerio (Llorens et al. 2009). Its name is an acronym derived from “Zebrafish Bel/Pao element”. Zebel element belongs to the Pao clade (Copeland et al. 2005) within Branch 2 of the Bel/Pao family (Llorens et al. 2009). The genome of Zebel is 7584 bp in lenght, including LTRs of 701 nt. The internal region of this LTR retrotransposon displays a single ORFs of 2033 amino acids showing the typical gag and pol protein domains of LTR retrotransposons (Llorens et al. 2009).

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
