SV40 large tumor antigen (Tag) was investigated by immunoprecipitation, silver staining, and Western blot analysis in 65 brain tumor cases and 8 cases of normal brain tissue. Tag‐p53 and Tag‐pRb complexes were screened by immunoprecipitation and Western blot analysis in 18 and 15 Tag positive tumor tissues, respectively.

Simian virus 40 (SV40) is a small, DNA-containing tumour virus. One of its gene products, the large tumour antigen (T-ag), is essential for both viral replication and cell transformation. SV40 T-ag can be considered a dual oncogene protein; it is a composite transforming protein that provides distinct functions at different subcellular locations.

Med tanke på den renade strukturen som ett individuellt antigen måste någon av Nonstrukturella proteinprodukter av tidiga adenovirusgener, SV 40-virus och 

In addition, the large T antigen binds DNA polymerase and the transcription factor AP-2 and forms a specific About SV40 large T antigen: 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. It also widely used for cell immortalization for variety of cell types. 2017-02-24 SV40 can express two early oncoproteins; small t-antigen (t-Ag) and large T antigen (T-Ag). T-Ag has been used to create a transgenic tumor mouse model and to transform cells for in vitro study ( 18 ).

1986-07-21 · The common region of SV40 ST, 17kT and LT proteins comprises the J domain. This domain is essential for multiple viral activities, including virion assembly, viral DNA replication, transformation and transcriptional activation. This domain is also required for cyclin A-transactivating activity of ST. 1 Publication 2017-04-14 · Study of SV40 large T antigen nucleotide specificity for DNA unwinding. Wang D(1), Álvarez-Cabrera AL(2), Chen XS(3)(4)(5). Author information: (1)Genetic, Molecular, and Cellular Biology Program, Keck School of Medicine, University of Southern California, Los Angeles, 90033, CA, USA. 2009-02-20 · The A gene of SV40 encodes large tumor antigen. SV40-induced tumors that were transplanted into fresh syngeneic hosts were rejected and cleared. The antigen that induced this rejection was termed tumor specific transplantation antigen or tsta (Defendi, 1963, Khera et al., 1963, Koch and Sabin, 1963).

2017-02-24 SV40 can express two early oncoproteins; small t-antigen (t-Ag) and large T antigen (T-Ag).

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. In addition, the large T antigen binds DNA polymerase and the transcription factor AP-2 and forms a specific About SV40 large T antigen: 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.

SV40 T-antigen transformed nasopharyngeal epithelial cells contained free, wild-type p53. Moreover, LMP1 regulated p53 both at transcriptional and translational level. These results strongly indicate that the association of topo I with these six residues in T antigen is essential for DNA replication.

It also widely used for cell immortalization for variety of cell types. 2017-02-24 SV40 can express two early oncoproteins; small t-antigen (t-Ag) and large T antigen (T-Ag).
