Here we show that the translesion synthesis DNA polymerase eta (Pol eta) plays a role in DNA replication under low deoxyribonucleotides condition triggered by hydroxyurea. In particular, the catalytic reaction performed by Pol eta is detrimental for RNase H deficient cells, causing DNA damage checkpoint activation and G2/M arrest

these findings provide insight into the physiological role of DNA synthesis by pol eta and have implications for our understanding of how our genome is replicated to avoid mutagenesis, genome instability and cancer
Title: DNA polymerase η contributes to genome-wide lagging strand 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...

These data indicate that under certain conditions, pol eta can compete with the cell's replicases and gain access to undamaged genomic DNA.
Title: Unlocking the steric gate of DNA polymerase η leads to increased genomic instability in Saccharomyces cerevisiae.
The stability of Pol eta, but not its mRNA level, is cell cycle stage dependent. The half-life of the polymerase is more than fourfold shorter in G1-arrested cells than in those at G2/M.
Title: The steady-state level and stability of TLS polymerase eta are cell cycle dependent in the yeast S. cerevisiae.

DNA polymerase eta (pol eta); involved in translesion synthesis during post-replication repair; catalyzes synthesis of DNA opposite cyclobutane pyrimidine dimers and other lesions; involved in formation of post-replicative damage-induced genome-wide cohesion; may also have role in protection against mitochondrial mutagenesis; may possibly be involved in meiosis; mutations in human pol eta are responsible for XPV
