Repeated tertiary fold of RNA polymerase II and implications for DNA binding.
نویسندگان
چکیده
X-ray diffraction data from two forms of yeast RNA polymerase II crystals indicate that the two largest subunits of the polymerase, Rpb1 and Rpb2, may have similar folds, as is suggested by secondary structure predictions. DNA may bind between the two subunits with its 2-fold axis aligned to a pseudo 2-fold axis of the protein.

Alpha-Amanitin resistance of RNA polymerase II in mutant Chinese hamster ovary cell lines.
A number of mutant Chinese hamster ovary (CHO) cell lines resistant to the cytotoxic action of alpha-amanitin have been isolated. The alpha-amanitin sensitivity of the different mutant cell lines varied widely, but correlated well with the alpha-amanitin sensitivity of the RNA polymerase II activity in each of these mutant cell lines. In comparison with the RNA polymerase II of wild-type cells,...

A number of mutant Chinese hamster ovary (CHO) cell lines resistant to the cytotoxic action of n-amanitin have been isolated. The a-amanitin sensitivity of the different mutant cell lines varied widely, but correlated well with the au-amanitin sensitivity of the RNA polymerase II activity in each of these mutant cell lines. In comparison with the RNA polymerase II of wild-type cells, three muta...
متن کاملThe splicing factor, Prp40, binds the phosphorylated carboxyl-terminal domain of RNA polymerase II.
We showed previously that the WW domain of the prolyl isomerase, Ess1, can bind the phosphorylated carboxyl-terminal domain (phospho-CTD) of the largest subunit of RNA Polymerase II. Analysis of phospho-CTD binding by four other WW domain-containing Saccharomyces cerevisiae proteins indicates the splicing factor, Prp40, and the RNA polymerase II ubiquitin ligase, Rsp5, can also bind the phospho...
متن کاملKu autoantigen is the regulatory component of a template-associated protein kinase that phosphorylates RNA polymerase II.
The carboxyl-terminal domain of RNA polymerase II contains a tandemly repeated heptapeptide sequence. Previous work has shown that this sequence is phosphorylated at multiple sites by a template-associated protein kinase, in a reaction that is closely associated with the initiation of RNA synthesis. We have purified this kinase to apparent homogeneity from human (HeLa) cells. The purified kinas...

Aptamers are the artificial single-stranded DNA or RNA sequences (more recently, peptides) that fold into secondary and tertiary structures making them bind to certain targets with extremely high specificity. Aptamers were reported for the first time in 1990, a number of their unique features make them a more effective choice than antibodies. Aptamers typically generated through Systematic Ev...
