Overlapping homologous superfamilies


Family relationships



Equine arteritis virus (EAV) is an enveloped, positive-strand RNA virus belonging to the family Arteriviridae. EAV virions contain six different envelope proteins. GP5 (previously named GL) and the unglycosylated membrane protein M are the major envelope proteins, while the glycoproteins GP2b (previously named Gs), GP3, and GP4 are minor structural proteins [PMID: 14645556]. GP2b is a class I transmembrane protein which adopts a number of different conformations [PMID: 8938984, PMID: 7745690].
