PCretro3 is a Ty1/Copia-like LTR retrotransposon found in the white rot fungus Phanerochaete chrysosporium (Novikova et al 2005, unpublished). It belongs to pCretro clade within Branch 2 of the Ty1/Copia LTR retrotransposons family (Llorens et al. 2009).

The genome of pCretro3 is 5088 bp in size, including two 402 bp LTRs that flank one single Open Reading Frame (ORF) of 1338 amino acids. This retroelement encodes for the gag-pol polyprotein which domains organization is the typical of Ty1/Copia LTR retrotransposons (gag, protease, integrase, reverse transcriptase and ribonuclease H).



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
