Asp-286----Asn-286 in polyomavirus large T antigen relaxes the specificity of binding to the polyomavirus origin.

We isolated revertants of a polyomavirus whose origin of DNA replication contains a point mutation in the palindrome to which large T antigen binds. Four independent second-site revertants contain an Asp-286----Asn-286 substitution in large T antigen. This mutant large T antigen activates replication of DNAs containing the mutant polyomavirus origin as well as replication of DNAs containing the...

Asymmetric assembly of Merkel cell polyomavirus large T-antigen origin binding domains at the viral origin.

The double-stranded DNA polyomavirus Merkel cell polyomavirus (MCV) causes Merkel cell carcinoma, an aggressive but rare human skin cancer that most often affects immunosuppressed and elderly persons. As in other polyomaviruses, the large T-antigen of MCV recognizes the viral origin of replication by binding repeating G(A/G)GGC pentamers. The spacing, number, orientation, and necessity of repea...

Determination of the origin-specific DNA-binding domain of polyomavirus large T antigen.

To map the DNA-binding domain of polyomavirus large T antigen, we constructed a set of plasmids coding for unidirectional carboxy- or amino-terminal deletion mutations in the large T antigen. Analysis of origin-specific DNA binding by mutant proteins expressed in Cos-1 cells revealed that the C-terminal boundary of the DNA-binding domain is at or near Glu-398. Fusion proteins of large T antigen...

Polyomavirus large T antigen binds cooperatively to its multiple binding sites in the viral origin of DNA replication.

Polyomavirus large T antigen binds to multiple 5'-G(A/G)GGC-3' pentanucleotide sequences in sites 1/2, A, B, and C within and adjacent to the origin of viral DNA replication on the polyomavirus genome. We asked whether the binding of large T antigen to one of these sites could influence binding to other sites. We discovered that binding to origin DNA is substantially stronger at pH 6 to 7 than ...

Polyomavirus large T antigen binds the transcriptional coactivator protein p300.

Using coimmunoprecipitation and glutathione S-transferase pulldown experiments, we found that polyomavirus large T antigen binds to p300 in vivo and in vitro. The N-terminal region of the viral protein, including the pRB binding motif, was dispensable for this interaction, which involved several regions within the C-terminal half of the large T antigen. Interestingly, anti-T antibody coimmunopr...
