Description

Cubel is a LTR retrotransposon found in the genome of the mosquito Culex quinquefasciatus (Llorens et al. 2009). Its name is an acronym derived from “Culex quinquefasciatus Bel/Pao element”. Cubel belongs to the Pao clade (Copeland et al. 2005) within Branch 2 of the Bel/Pao family (Llorens et al. 2009). Cubel genome is 7632 bp long, including LTRs of respectively 777 (5’-LTR) and 776 nts (3’-LTR). The internal region of this LTR retrotransposon displays a single ORF encoding for both gag and pol genes characteristics 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
