A neutralizing antibody against human DNA polymerase ε inhibits cellular but not SV40 DNA replication
The contribution of human DNA polymerase ε to nuclear DNA replication was studied. Antibody K18 that specifically inhibits DNA polymerase activity of human DNA polymerase ε in vitro significantly inhibits DNA synthesis both when microinjected into nuclei of exponentially growing human fibroblasts and in isolated HeLa cell nuclei. The capability of this neutralizing antibody to inhibit DNA synth...
متن کاملSimian virus 40 (SV40) small t antigen inhibits SV40 DNA replication in vitro.
We describe a biochemical function of simian virus 40 small t antigen, the inhibition of simian virus 40 large T antigen-mediated viral DNA replication in an in vitro replication system. Our results suggest that in this system, small t antigen prevents protein phosphatase 2A-mediated activation of large T antigen.
متن کاملSimian virus 40 (SV40) DNA replication: SV40 large T antigen unwinds DNA containing the SV40 origin of replication.
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 of a circular duplex DNA molecule containing the SV40 origin of replication to a form with unusual electrophoretic mobility that we have named form U. Analysis of this molecule revealed it to be a highly underwound covalently closed circ...
متن کاملModeling of the SV40 DNA Replication Machine
The mechanism of SV40 DNA replication is certainly not completely understood. The proteins that are necessary for replication have been known for quite some time, but how they work together to form a nanomachine capable of faithfully replicating the virus DNA is only partially understood. Some of the proteins involved have been crystallized and their 3D structures determined, and several EM rec...
