Biochemical studies on structural and nonstructural proteins of the African green monkey B-lymphotropic papovavirus (LPV). 1983

L Brade, and N Mueller-Lantzsch, and S Kaiser, and M Scharrer

African green monkey (AGM) B-lymphotropic papovavirus (LPV) particles were separated from infected B-lymphoma BJA-B cells by neuraminidase and deoxycholate treatment and were further purified twice by CsCl density centrifugation. The SDS-PAGE analysis of virus particles banding at a density of 1.3510 g/ml and radioactively labeled by 125I revealed a major polypeptide of 40,000 and two minor polypeptides of 42,000 and 29,000. In addition, in infected BJA-B cells, all three viral structural polypeptides could be identified by immunoprecipitation. A nonstructural phosphopolypeptide of approximately 90,000 MW could be detected when sera against SDS-denatured SV40 T antigen or an AGM serum pool were used for immunoprecipitation. It is suggested that the 90K polypeptide of LPV represents an equivalent to T antigens of other papovaviruses.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015678 Viral Structural Proteins Viral proteins that are components of the mature assembled VIRUS PARTICLES. They may include nucleocapsid core proteins (gag proteins), enzymes packaged within the virus particle (pol proteins), and membrane components (env proteins). These do not include the proteins encoded in the VIRAL GENOME that are produced in infected cells but which are not packaged in the mature virus particle,i.e. the so called non-structural proteins (VIRAL NONSTRUCTURAL PROTEINS).
