What's a GeneRIF?

Structure and mechanism of B-family DNA polymerase zeta specialized for translesion DNA synthesis.
Title: Structure and mechanism of B-family DNA polymerase ζ specialized for translesion DNA synthesis.
Profiles of base-substitutions created by Polzeta & Poleta of Saccharomyces cerevisiae were analyzed. Poleta created deletions at the lesion in more than 50% of the TLS products, but the formation of the deletions was suppressed by the presence of Polzeta. Polzeta & Poleta cooperatively facilitated the TLS reaction over an abasic site in vitro, suggesting that these two polymerases can cooperate in efficient and high f...
Title: NGS-based analysis of base-substitution signatures created by yeast DNA polymerase eta and zeta on undamaged and abasic DNA templates in vitro.
This study also uncovered an important role for Rev3 and Rev7 (but not for Pol32) subunits of polymerase z in the survival of cells undergoing telomere losses and forming palindromes
Title: Telomere Dysfunction Triggers Palindrome Formation Independently of Double-Strand Break Repair Mechanisms.
Pol zeta, the enzyme responsible for the majority of damage-induced mutagenesis in eukaryotes, the two-subunit (Rev3-Rev7) form of yeast Pol zeta used in this study suggest that ribonucleotide incorporation into DNA during Pol zeta-mediated mutagenesis in vivo may be rare.
Title: Ribonucleotide incorporation by yeast DNA polymerase ζ.
in addition to extending aberrant termini created by other DNA polymerases, Pol zeta has the potential to be the sole DNA polymerase involved in translesion synthesis
Title: Lesion bypass by S. cerevisiae Pol ζ alone.
the 9-1-1 clamp, made of Ddc1, Rad17, and Mec3, may physically regulate Polzeta-dependent mutagenesis by controlling the access of Polzeta to damaged DNA
Title: The 9-1-1 checkpoint clamp physically interacts with polzeta and is partially required for spontaneous polzeta-dependent mutagenesis in Saccharomyces cerevisiae.
DNA polymerase zeta and Rev1 proteins function in the mitochondria
