polι, a remarkably error-prone human DNA polymerase
Open accessAbstract
The Saccharomyces cerevisiae RAD30 gene encodes DNA polymerase η. Humans possess two Rad30 homologs. One ( RAD30A/POLH ) has previously been characterized and shown to be defective in humans with the Xeroderma pigmentosum variant phenotype. Here, we report experiments demonstrating that the second human homolog ( RAD30B ), also encodes a novel DNA polymerase that we designate polι. polι, is a distributive enzyme that is highly error-prone when replicating undamaged DNA. At template G or C, the average error frequency was ∼1 × 10 −2 . Our studies revealed, however, a striking asymmetry in misincorporation frequency at template A and T. For example, template A was replicated with the greatest accuracy, with misincorporation of G, A, or C occurring with a frequency of ∼1 × 10 −4 to 2 × 10 −4 . In dramatic contrast, most errors occurred at template T, where the misincorporation of G was, in fact, favored ∼3:1 over the correct nucleotide, A, and misincorporation of T occurred at a frequency of ∼6.7 × 10 −1 . These findings demonstrate that polι is one of the most error-prone eukaryotic polymerases reported to date and exhibits an unusual misincorporation spectrum in vitro.

In the citing paper
“The most striking violation of Watson-Crick base pairing rules is exhibited by Pol , which inserts dGTP opposite template T even more efficiently than it inserts A opposite T (12-14), i.e. its error rate for this mispair approaches 1 (Fig. 1).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
