| Name | endogenous retrovirus group V, member 1 |
| Description | Many different human endogenous retrovirus (HERV) families are expressed in normal placental tissue at high levels, suggesting that HERVs are functionally important in reproduction. This gene is part of an HERV provirus on human chromosome 19 that has inactivating mutations in the gag and pol genes. The gene's envelope protein is expressed in the human placenta but is truncated at its C-terminus. [provided by RefSeq, Oct 2015] |
| Summary |
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n Endogenous retroviral envelope genes of the ERV‐V family have been co‐opted during evolution for roles in placentation. One such gene, ERVV‐1, is expressed in human trophoblasts as a member of the syncytin family. In certain primate lineages—for example, in Old World monkeys—the related envV gene exhibits potent fusogenic activity that promotes cell–cell fusion and facilitates the formation of the syncytiotrophoblast, a critical structure at the materno–fetal interface."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": " In contrast, in other primates, including humans, ERVV‐1 has lost this canonical fusogenic function through a gradual, multi‐step evolutionary process. Although ERVV‐1 is still transcriptionally active in placental tissues—as shown by its inclusion among the several ERV‐derived syncytin family members—it appears that its direct role in mediating trophoblast fusion is minimal or absent, which raises the possibility that it may have been repurposed for other, as‐yet‐undefined regulatory functions in placental development."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": " Collectively, these studies indicate that ERVV‐1 exemplifies how evolutionary pressures have shaped ERV‐derived genes: while some members (such as ERVW1 and ERVFRD1) retain robust fusogenic activity essential for syncytiotrophoblast formation, others like ERVV‐1 have undergone functional changes that may alter or refine their influence on placental biology. Further research is warranted to elucidate whether ERVV‐1 contributes to placentation through nonfusogenic roles or if it acts in concert with other syncytins in a redundant or modulatory capacity.\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Cécile Esnault, Guillaume Cornelis, Odile Heidmann, et al.
