Human endogenous retrovirus (HERV) proteins

Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

Show »« Hide

Endogenous retrovirus (ERV) genes [8] are elements of ancient exogenous retroviruses that have been retained and selectively preserved in the human germline [2]. Their protein products play roles in normal physiological processes and in disease pathology.

Comment

An ancient retroviral gene that is integrated into the human genome, and the expressed HERV-W ENV protein retains its original fusogenic activity. Expressed in the placenta where it is involved in trophoblast fusion and syncytium formation [2]. Evidence indicates that it plays immunopathogenic roles in inflammatory and neurological diseases [6] and is associated with the development of multiple sclerosis [5] and type 1 diabetes [7]. HERV-W ENV can be activated by exogenous viruses [3]; elevated expression has been detected in T cells from COVID-19 patients [1].
