Genomic localization of hog cholera virus glycoproteins

A polyspecific antiserum has been used to identify four different glycoproteins in hog cholera virus (HCV)-infected cells termed gp55, gp48, gp44, and gp33 (Rümenapf et al, 1989, Virology 171, 18-27). Fusion proteins containing parts of the putative HCV-encoded glycoproteins were expressed in bacteria and served for the preparation of specific antibodies. These were used in radioimmunoprecipitation assays which revealed that gp48 and gp44 most likely share a common protein backbone. The order of the glycoproteins on the HCV genome was determined as follows: NH2-gp44/gp48-gp33-gp55-COOH.
