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 …

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. SV40 is an abbreviation for simian vacuolating virus 40 or simian virus 40, a polyomavirus that is found in both monkeys and humans. Like other polyomaviruses, SV40 is a DNA virus that has the potential to cause tumors in animals, but most often persists as a latent infection. Simian virus 40 (SV40) is a member of the Polyomaviridae, a family of viruses characterized by small icosahedral virions and a circular double-stranded DNA genome of about 5 kb.

pages 36 sidor. 279,00 kr SV40 large T antigen (Simian Vacuolating Virus 40 TAg) is a hexamer protein that is a dominant-acting oncoprotein derived from the polyomavirus SV40. TAg is capable of inducing malignant transformation of a variety of cell types.

härledd från SV40 T-antigen vid N-terminalen av vildtyp och K487R-mutant. ( b ) Kärnlokaliseringssekvensen SV-40 infördes i HA-PML4-konstruktioner

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 complex with the P105 product of the retinoblastoma susceptibility gene.

CRL-11,268).. Culture medium: Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% fetal calf serum, 100 U/ml penicillin and 100 μg/ml streptomycin.. The 293T cells are maintained in the above culture medium at 37 °C and 5% CO 2 in Description. SV40 large T antigen NLS is from Large T antigen residue 47 to 55, enables protein import into cell nucleus. 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).T-ag NLS can enhance nuclear import, despite the fact that PK-C has been shown to inhibit nuclear import of proteins such as lamin B2. Adeno-associated virus (AAV) inhibits the induction of host DNA synthesis by simian virus 40 (SV40) large-tumour (T) antigen, mediated through AAV-encoded 'Rep' regulatory proteins.
