Abstract

The recently released draft horse genome is incompletely characterised in terms of its repetitive

element proﬁle. This paper presents characterisation of the endogenous retrovirus (ERVs) of the horse

genome based on a data-mining strategy using murine leukaemia virus proteins as queries. 978 ERV

gene sequences were identiﬁed. Sequences were identiﬁed from the gamma, epsilon and betaretrovirus

genera. At least one full length gammaretroviral locus was identiﬁed, though the gammaretroviral

sequences are very degenerate. Using these data the RNA expression of these ERVs were derived from

RNA transcriptome data from a variety of equine tissues. Unlike the well studied human and murine

ERVs there do not appear to be particular phylogenetic groups of equine ERVs that are more

transcriptionally active. Using this novel approach provided a more technically feasible method to

characterise ERV expression than previous studies.
