We have sequenced and characterized an endogenous type D
retrovirus, which we have named TvERV(D), from the genome of an
Australian marsupial, the common brushtail possum (Trichosurus
vulpecula). Intact TvERV(D) gag, pro, pol, and
env open reading frames were detected in the possum genome.
TvERV(D) was classified as a type D retrovirus, most closely related to
those of Old World monkeys, New World monkeys, and mice, based on
phylogenetic analyses and genetic organization. Approximately 30 TvERV(D) proviruses are present in the genomes of possums, as detected
by Southern hybridization. However, variability in fragment patterns
between possums was observed and suggests recent (or ongoing)
retrotranspositional activity.
