Element:Tse1

Description Tse1 is a Ty1/Copia LTR retroelement described in the genome of the hemiascomycetous yeast Kazachstania exigua (syn. Saccharomyces exiguus) (Neuvéglise et al. 2002). It belongs to the Ty (Pseudovirus) clade one of the three original genera on which the in-progrees Pseudoviridae classification is constituted (Boeke et al 2005). The genome of Tse1 is about of 5.7 Kb in size (5691 bp long), including two 424-bp LTRs (Neuvéglise et al. 2002). The internal region of this element presents a Primer Binding Site (PBS) and two overlapping Open Reading Frames (ORFs). The first ORF displays the gag domains, while the second larger ORF presents the typical Ty1/Copia pol polyprotein structure: protease, integrase, reverse transcriptase and RNase H (Neuvéglise et al. 2002). 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.
