HERVH (DF0000183)

Internal region of ERV1 endogenous retrovirus, HERVH subfamily


The long terminal repeat associated with HERVH is LTR7. The putative env gene, consisting of about 1800 base pairs, has two open reading frames interrupted by a termination codon. The amino acid sequence of this region shows significant homology to those of other retroviral envelope proteins and contains eight potential glycosylation sites. It is estimated that there are about 100 copies of RTVL-H elements containing the env gene per haploid human genome. Note that this estimate is distinct from simply tallying all hits (long and short) from this model.
