Background InformationHuman endogenous retrovirus (HERV) proviruses comprise a significant part of the human genome, with approximately 98,000 ERV elements and fragments making up nearly 8% of the DNA. All appear to be inactive containing many deletions and nonsense mutations having integrated into the genome likely millions of years ago but left over HERV DNA as played an active role in genome evolution for millions and years and many important genes expressed today have promoters and enhances that have come from HERV DNA sequences. The best studied example is that of the retroviral fusogenic env proteins. In humans, and other mammals, intact env proteins called syncytins are responsible for the formation and function of syncytiotrophoblasts. These multi-nucleated cells are mainly responsible for maintaining nutrient exchange and protecting the developing fetus from the mother's immune system. The protein HERV-WL is an ancient retroviral envelope (env) protein. This endogenous envelope protein has retained its original fusogenic properties and participates in trophoblast fusion during placenta morphogenesis. HERV-WL gets cleaved into two functional chains upon expression. A surface protein named SU and a transmembrane protein called TM. SU mediates receptor recognition. This interaction triggers the refolding of the transmembrane protein (TM) and is thought to activate its fusogenic potential by unmasking its fusion peptide. The transmembrane protein (TM) acts as a class I viral fusion protein. 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. HERV is expressed during development and in the uterine and placental tissues in the adult.
