2017-04-14 · BACKGROUND: Simian Virus 40 (SV40) Large Tumor Antigen (LT) is an essential enzyme that plays a vital role in viral DNA replication in mammalian cells. As a replicative helicase and initiator, LT assembles as a double-hexamer at the SV40 origin to initiate genomic replication. 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.

Expression of T antigen from SV40, Human 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 SV40 large T antigen (TAg) is a powerful oncoprotein capable of transforming a variety of cell types. The transforming activity of TAg is due in large part to its perturbation of the retinoblastoma (pRB) and p53 tumor suppressor proteins. In addition, TAg binds to several other cellular factors, inc …. SV40 large T antigen (TAg) is a powerful One of the frequently used genes for immortalization is the SV40 virus large T-antigen (TAg), which overcomes p53 and pRB dependent cell cycle arrest . A thermolabile mutant has been isolated ( 2 ) and used in the creation of conditionally immortalized cells ( 3 , 4 ). This is clearly shown during SV40 productive infections where T antigen levels rise during the first 24 h postinfection, but then reach a steady-state level.

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factors SV40 large T antigen for immortalizing cells David Ron Lab: SV40 large T antigen for immortalizing cells Unpublished.

Some of these  or to the nucleus (addition of the nuclear localization sequence of SV40 large T antigen) resulted in preferential accumulation of hGH in the nucleus. 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.

You're viewing: SV40 large T antigen NLS £70.20. [16]. SV40 shares a similar genomic structure to other polyomavirus, where a large non-coding region controls the expression of the early and late transcribed regions of the genome.

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.

A GFP-Puromycin fusion dual marker was expressed under RSV promoter, which allows to select via Puromycin antibiotic or sort via GFP signal, the transduced cells (Dual markers). GFP signal provides a convenient transduction monitoring for virus performance. version of the SV40 large T antigen.5,6 The SV40 large T antigen is known to be capable of transforming human and rodent cells in vitro and in vivo. Also SV40-transformed human cells are able to produce tumors when administered to nude mice.7,8 Therefore, the presence of residual SV40 T antigen protein and/or T anti- SV40 large T antigen .

This is clearly shown during SV40 productive infections where T antigen levels rise during the first 24 h postinfection, but then reach a steady-state level. Mutation of the T antigen binding sequences in the early promoter eliminate this autoregulation and lead to constituitively high levels of T antigen. Large T antigen is also a transcriptional activator.
