Endogenous retroviruses (ERVs) are endogenous viral elements in the genome that closely resemble and can be derived from retroviruses. They are abundant in the genomes of jawed vertebrates , and they comprise up to 5–8% of the human genome (lower estimates of ~1%).
Human Endogenous Retrovirus-W (HERV-W) is a family of Human Endogenous Retroviruses (HERVs). HERVs are part of a superfamily of repetitive and transposable elements . Transposable elements are sequences of DNA that can move or "jump" around the genome, sometimes replicating and inserting themselves in different locations.
The human endogenous retrovirus K (HERV-K) was inherited million years ago by the genome of the human ancestors. [18] In 1999 Barbulescu, et al. showed that, of ten HERV-K proviruses cloned, eight were unique to humans, while one was shared with chimpanzees and bonobos , and one with chimpanzees, bonobos and gorillas . [ 19 ]
When retroviruses have integrated their own genome into the germ line, their genome is passed on to a following generation. These endogenous retroviruses (ERVs), contrasted with exogenous ones, now make up 5–8% of the human genome. [21] Most insertions have no known function and are often referred to as "junk DNA".
The human genome includes many retroelements including the human endogenous retroviruses (HERVs), which compose about 7-8% of the human genome. [5] ERV3, one of the most studied HERVs, is thought to have integrated 30 to 40 million years ago and is present in higher primates with the exception of gorillas.

Syncytin-2 also known as endogenous retrovirus group FRD member 1 is a protein that in humans is encoded by the ERVFRD-1 gene. [5] This protein plays a key role in the implantation of human embryos in the womb. [6] This gene is conserved among all primates, with an estimated age of 45 million years. The receptor for this fusogenic env protein ...
