Element:Yoyo

Description Yoyo is a retrovirus characterized in the genome of Ceratitis capitata (Zhou and Haymer 1996) and belongs to the genus Errantiviridae (Boeke et al. 1999; Pringle 1998; 1999; Hull 1999), a lineage of fly-retroviruses and LTR retrotransposons phylogenetically related to 412/mdg1 clade (Tubio, Naveira and Costas 2005). The genomic structure of Yoyo is 7.7 Kb in size including LTRs of 316 nt. The internal region displays a Primer Binding Site (PBS) complementary to a tRNALys, three Open Reading Frames (ORFs) for gag, pol, and env genes, and a Polypurine Tract (PPT) adjacent to the 3´LTR (Zhou and Haymer 1996). 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.
