The cell line is generated from E12,5 rat raphe nucleus and transduced with the temperature sensitive mutant of the Simian Virus 40 (SV40) large T-antigen.

SV40 T antigen is encoded by the early region of the SV40 genome. The large T antigen binds DNA, and complexes with a 53,000 dalton cellular protein, p53, which is required for initiation of viral DNA replication during lytic growth.

SV40 large T antigen Contents. TAg is a product of an early gene transcribed during viral infection by SV40, and is involved in viral genome Domains. The TAg has a CUL7 -binding domain, a TP53 -binding domain, a Zinc finger, and a Superfamily 3 ATPase/Helicase Mechanism. After entering the For examples, SV40 has the large T antigen that binds SV40 DNA replication origin and has helicase activity, and also recruits the replication machinery by interacting with DNA replication factors SV40 large T antigen for immortalizing cells David Ron Lab: SV40 large T antigen for immortalizing cells Unpublished.

Subscribe SV40 Tantigen contains a helicase activity that, in the presence of a single-stranded DNA binding protein, can extensively unwindthe template DNA.Inclusion of E. coli Binds two adjacent sites in the SV40 origin. The replication fork movement is facilitated by Large T antigen helicase activity. Activates the transcription of viral late mRNA, through host TBP and TFIIA stabilization. Interferes with histone deacetylation mediated by HDAC1, leading to … SV40 large T antigen (click to see its coding sequence), [Simian Vacuolating Virus 40 Large T-Ag ] is a hexamer protein involved in viral genome replication and regulation of the host cell cycle. It is used as a model protein to study nuclear localization signals and viral replication.

mutant large T antigen origin-binding domain formed higher oligomeric products in a redox-dependent manner; These studies refine the understanding of how the large T antigen origin-binding domain s encoded by the polyomavirus family interact with single-stranded DNA, a critical step during the initiation of DNA replication. (a) SV40 genomic DNA is composed of three elements: the early and late coding units and the regulatory region. The early unit encodes large T antigen (LT), small t antigen (sT), 17K T antigen The biochemical properties of the large T antigens encoded by simian virus 40 (SV40) mutants with deletions at DdeI sites in the SV40 A gene were determined. Mutant large T antigens containing only the first 138 to 140 amino acids were unable to bind to the SV40 origin of DNA replication as were large T antigens containing at their COOH termini 96 or 97 amino acids encoded by the long open reading frame located between 0.22 and 0.165 map units (m.u.). Isoform large T antigen is a key early protein essential for both driving viral replication and inducing cellular transformation.
