Human endogenous retrovirus K

Human endogenous retrovirus K (HERVK) is a family of endogenous retroviruses in humans.[1] HERVK is also found in apes and Old World monkeys.

In 1999 Barbulescu, et al. showed that, of ten HERVK proviruses cloned, eight were unique to humans, while one was shared with chimpanzees and bonobos, and one with humans, chimpanzees and bonobos and gorillas.[2]

In 2015 Grow et al. demonstrated that HERVK is transcribed during embryogenesis from the eight cell stage up to the stem cell derivation.[3] Furthermore, the overexpression the HERVK accessory protein Rec increases IFITM1 levels on the cell surface and inhibits viral infection.[3]
