The 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. In addition, the large T antigen binds DNA polymerase and the transcription factor AP-2 and forms a specific Large T antigen. Gene. N/A. Organism. Simian virus 40 (SV40) Status.

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.

The simian virus 40 (SV40) large T antigen (large tumor antigen), in conjunction with a topoisomerase, a DNA binding protein, and ATP, catalyzed the conversion Background/Aims: DNA sequences from Simian virus 40. (SV40) have been previously isolated from various human tumours of the central nervous system natriuretic factor (a hormone intimately involved in the regulation of blood pressure) and those encoding SV40 T antigen (an oncoprotein) were generated. We have generated a transgenic rat with the SV40 T antigen under probasin promoter control, allowing prostate-specific gene expression. Males demonstrate 13 Apr 2018 The SV40 T antigen has been widely used in biological research as an inducerof cell line immortalization and as well for the generation of Expression of E6/E7 or SV40 large T antigen-coding oncogenes in human corneal endothelial cells indicates regulated high-proliferative capacity.

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.).

Tag‐p53 and Tag‐pRb complexes were screened by immunoprecipitation and Western blot analysis in 18 and 15 Tag positive tumor tissues, respectively. One of the most commonly used immortalizing genes is SV40 T antigen –. We and others previously used retroviral vector-mediated expression of SV40 T antigen to immortalize primary cells –. SV40 packs all of its functional needs into one remarkable, multifunctional protein. The T-antigen is composed of several functional parts, connected by flexible linkers.

In Vitro. SV40 large tumor-antigen (T-ag) nuclear import is enhanced by the protein kinase CK2 (CK2) site (Ser111Ser112) flanking the nuclear localization sequence (NLS)[1]. Both the RB1 protein and the product of this gene can form a complex with adenovirus E1A protein and SV40 large T-antigen, with the SV40 large T-antigen binding only to the unphosphorylated form of each protein. In addition, both proteins can inhibit the transcription of cell cycle genes containing E2F binding sites in their promoters. 2017-02-21 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.

In rats, the oncogenic SV40 large T antigen was used to establish a brain tumor model for primitive neuroectodermal tumor and medulloblastoma. [23] The molecular mechanisms by which the virus reproduces and alters cell function were previously unknown, and research into SV40 vastly increased biologists' understanding of gene expression and the regulation of cell growth. The SV40 T antigen genome was amplified in 4 of the 13 ependymomas (31%) and 3 of the 20 other histotypes of gliomas (15%), whereas in the 22 nontumoral brain tissue specimens, only one case was found to be positive.

Sharma S, Rodgers L, Brandsma J, Gething MJ, Sambrook J. A chimeric gene consisting of DNA coding for the 15-amino acid signal peptide of influenza virus hemagglutinin and the C-terminal 694 amino acids of SV40 large T antigen was inserted into a bovine papilloma virus (BPV) expression vector and introduced into NIH-3T3 cells. 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. The SV40 genome is organized in three specific areas: (i) a non-coding control region (NCCR) which includes the origin of DNA replication, (ii) the early genes which code for large T antigen (Tag) and small t antigen, and (iii) the late genes encoding the capsid proteins VP-1, VP-2 and VP-3, and the agnoprotein (6, 10, 11). SV40 Viral Vectors for Cell Immortalization SV40 T antigen has been shown to be the most simple and reliable agent for the transfromation of many different cell types in culture. The mechanism of SV40 T antigen in cell immortalization is well studied.
