Dendrogram of various classes of endogenous retroviruses. 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%). [1] [2]
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 ...
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.
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.

A retrovirus is a type of virus that inserts a DNA copy of its RNA genome into the DNA of a host cell that it invades, thus changing the genome of that cell. [2] After invading a host cell's cytoplasm, the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backward).

In humans this protein is called syncytin, and is encoded by an endogenous retrovirus called on chromosome seven. Remarkably, the capture of syncytin or syncytin-like genes has occurred independently, from different groups of endogenous retroviruses, in diverse mammalian lineages .
