An endogenous retroviral envelope syncytin and its cognate receptor identified in the viviparous placental Mabuya lizard [Microbiology]

Syncytins are envelope genes from endogenous retroviruses that have been captured during evolution for a function in placentation. They have been found in all placental mammals in which they have been searched, including marsupials. Placental structures are not restricted to mammals but also emerged in some other vertebrates, most frequently...
