The DNA polymerase activity of Saccharomyces cerevisiae Rev1 is biologically significant.
A cell's ability to tolerate DNA damage is directly connected to the human development of diseases and cancer. To better understand the processes underlying mutagenesis, we studied the cell's reliance on the potentially error-prone translesion synthesis (TLS), and an error-free, template-switching pathway in Saccharomyces cerevisiae. The primary proteins mediating S. cerevisiae TLS are three DN...
متن کاملProteasomal regulation of the mutagenic translesion DNA polymerase, Saccharomyces cerevisiae Rev1.
Translesion DNA synthesis (TLS) functions as a tolerance mechanism for DNA damage at a potentially mutagenic cost. Three TLS polymerases (Pols) function to bypass DNA damage in Saccharomyces cerevisiae: Rev1, Pol ζ, a heterodimer of the Rev3 and Rev7 proteins, and Pol η (Rad30). Our lab has shown that S. cerevisiae Rev1 protein levels are under striking cell cycle regulation, being ∼50-fold hig...
متن کاملYeast Rev1 protein is a G template-specific DNA polymerase.
Rev1 protein of Saccharomyces cerevisiae functions with DNA polymerase zeta in mutagenic trans-lesion synthesis. Because of the reported preferential incorporation of a C residue opposite an abasic site, Rev1 has been referred to as a deoxycytidyltransferase. Here, we use steady-state kinetics to examine nucleotide incorporation by Rev1 opposite undamaged and damaged template residues. We show ...
متن کاملHuman Rev1 polymerase disrupts G-quadruplex DNA
The Y-family DNA polymerase Rev1 is required for successful replication of G-quadruplex DNA (G4 DNA) in higher eukaryotes. Here we show that human Rev1 (hRev1) disrupts G4 DNA structures and prevents refolding in vitro. Nucleotidyl transfer by hRev1 is not necessary for mechanical unfolding to occur. hRev1 binds G4 DNA substrates with Kd,DNA values that are 4-15-fold lower than those of non-G4 ...
متن کاملCisplatin cytotoxicity is dependent on mitochondrial respiration in Saccharomyces cerevisiae
Objective(s): To understand the role of mitochondrial respiration in cisplatin sensitivity, we have employed wild-type and mitochondrial DNA depleted Rho0 yeast cells. Materials and Methods: Wild type and Rho0 yeast cultured in fermentable and non-fermentable sugar containing media, were studied for their sensitivity against cisplatin by monitoring growth curves, oxygen consumption, pH changes ...
