Syncytin 1 is one of the best known examples of recent acquisition of a new gene from an endogenous retrovirus (HERV) in the human genome and has been implicated in placental physiology. Within primates, Syncytin 1 is conserved in all hominoids but has not been characterized in Old World monkeys (OWMs). In this study, we investigated the status of Syncytin 1 in 14 hominoid and OWM species. We show that although the HERV-W provirus responsible for the origin of this gene was present in the… CONTINUE READING
