Element:Tricopia

Description Tricopia is a LTR retrotransposon found in the genome of the red flour beetle Tribolium castaneum. It gives the name and constitutes a single clade within Branch 2 of the Ty1/Copia LTR retrotransposons family (Llorens et al. 2009). The genome of Tricopia is about of 4.5 Kb (4541 bp long), including LTRs of 260 (5’LTR) and 258 (3’LTR) bp long. The LTRs flanked internal region encodes for a single long ORF that, although is disrupted by some stop codons, contains the typical gag-pol domains structure of Ty1/Copia LTR retrotransposons (gag, protease, integrase, reverse transcriptase and ribonuclease H). 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.
