Entrez Gene Summary for ERVW-1 Gene

  • 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 chromosome 7 that has inactivating mutations in the gag and pol genes. This gene is the envelope glycoprotein gene which appears to have been selectively preserved. The gene's protein product is expressed in the placental syncytiotrophoblast and is involved in fusion of the cytotrophoblast cells to form the syncytial layer of the placenta. The protein has the characteristics of a typical retroviral envelope protein, including a furin cleavage site that separates the surface (SU) and transmembrane (TM) proteins which form a heterodimer. Alternatively spliced transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Mar 2010]

GeneCards Summary for ERVW-1 Gene

ERVW-1 (Endogenous Retrovirus Group W, Member 1) is a Protein Coding gene. Diseases associated with ERVW-1 include louping ill and murray valley encephalitis. An important paralog of this gene is ERVFRD-1.

UniProtKB/Swiss-Prot for ERVW-1 Gene

  • This endogenous retroviral envelope protein has retained its original fusogenic properties and participates in trophoblast fusion and the formation of a syncytium during placenta morphogenesis. May induce fusion through binding of SLC1A4 and SLC1A5 (PubMed:10708449, PubMed:12050356, PubMed:23492904).

  • Endogenous envelope proteins may have kept, lost or modified their original function during evolution. Retroviral envelope proteins mediate receptor recognition and membrane fusion during early infection. The surface protein (SU) mediates receptor recognition, while the transmembrane protein (TM) acts as a class I viral fusion protein. The protein may have at least 3 conformational states: pre-fusion native state, pre-hairpin intermediate state, and post-fusion hairpin state. During viral and target cell membrane fusion, the coiled coil regions (heptad repeats) assume a trimer-of-hairpins structure, positioning the fusion peptide in close proximity to the C-terminal region of the ectodomain. The formation of this structure appears to drive apposition and subsequent fusion of membranes

    Size:
    538 amino acids
    Molecular mass:
    59866 Da
    Quaternary structure:
    • The mature envelope protein (Env) consists of a trimer of SU-TM heterodimers attached probably by a labile interchain disulfide bond. Interacts with the C-type lectin CD209/DC-SIGN.
    Miscellaneous:
    • HERV-W family subgenomic RNAs have been observed
    • It can make pseudotypes with HIV-1 virions and confer infectivity. Can also induce cellular resistance to spleen necrosis virus in vitro
    • Orthologs in Pan troglodytes, Gorilla gorilla, Pongo pygmaeus and Hylobates moloch
    • Probably involved in the development of multiple sclerosis (MS). MS is a neurodegenerative disease characterized by the gradual accumulation of focal plaques of demyelination particularly in the periventricular areas of the brain. It leads to physical and cognitive disabilities. Viral particles or intracellular RNA of HERV-W family members have been detected in tissue from patients with multiple sclerosis or schizophrenia
    • The human genome contains a high percentage of proviral-like elements, also called endogenous retroviruses (ERVs) that are the genomic traces of ancient infections of the germline by exogenous retroviruses. Although most of these elements are defective, some have conserved a functional envelope (env) gene, most probably diverted by the host for its benefit
    • This provirus is intergenic, the closest flanking genes being ODAG and PEX1

Post-translational modifications for ERVW-1 Gene

  • Specific enzymatic cleavages in vivo yield mature proteins. Envelope glycoproteins are synthesized as a inactive precursor that is heavily N-glycosylated and processed likely by furin in the Golgi to yield the mature SU and TM proteins. The cleavage site between SU and TM requires the minimal sequence [KR]-X-[KR]-R. The intracytoplasmic tail cleavage by the viral protease that is required for the fusiogenic activity of some retroviruses envelope proteins seems to have been lost during evolution.
  • The CXXC motif is highly conserved across a broad range of retroviral envelope proteins. It is thought to participate in the formation of a labile disulfide bond possibly with the CX6CC motif present in the transmembrane protein. Isomerization of the intersubunit disulfide bond to an SU intrachain disulfide bond is thought to occur upon receptor recognition in order to allow membrane fusion (By similarity).
  • Glycosylation at Asn 169, Asn 208, Asn 214, Asn 234, Asn 242, Asn 281, and Asn 409
  • Modification sites at PhosphoSitePlus
