HERV17 (DF0000628)

Internal region of ERV1 endogenous retrovirus, HERV17 subfamily


LTRs of the class I HERV17 (aka HERV-W) are listed as LTR17 sequences. HERV17 is related to HERV9/pHE1 and was relatively recently (<20 Mya) active as copies of the younger subfamilies are < 6% diverged from the consensus (primarily at CpG sites). This contains ORFs at the following approximate positions: 1938-3143 (gag), 3670-6912 (pol) and 6940-8568 (env). A copy of the latter has been exapted as the human syncytin gene[1].
