Element:Koala

Description Koala is one of the several transposable elements described in the genome of the rice species Oryza australiensis (Piegu et al. 2006). This LTR retrotransposon belongs to Retrofit clade within the Branch 2 of the Ty1/Copia family (Llorens et al. 2009). The genome of Koala is 4992 bp in size, including LTRs of 315 nts that flank a single Open Reading Frame ORF. This encodes for both gag and pol polyproteins domains characteristic of Ty1/Copia LTR retrotransposons (Piegu et al. 2006). 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.
