Element:CoDi5.3

Description CoDi5.3, a Ty1/Copia LTR retrotransposon described in the genome of the marine pinnate diatom Phaeodactylum tricornutum (Maumus et al. 2009; Bowler et al. 2008). This element belongs to CoDi-II clade (Maumus et al. 2009) within Branch 1 of the Ty1/Copia family (Llorens et al. 2009). CoDi5.3 genome, of about 5.5 Kb in size (5553 bp long), includes a 239-bp 5'LTR and a 237-bp 3'LTR flanking an internal region that encodes a long Open Reading Frame (ORF) interrupted by one stop codon. The ORF contains the gag and pol typical structure of the Ty1/Copia LTR retrotransposons: gag, protease, integrase, reverse transcriptase and ribonuclease H (for more details, see Maumus et al. 2009). 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.
