Structure of the Helicase Domain of DNA Polymerase Theta Reveals a Possible Role in the Microhomology-Mediated End-Joining Pathway [PDF]

open access: yes, 2015
DNA polymerase theta (Polθ) has been identified as a crucial alternative non-homologous end-joining factor in mammalian cells. Polθ is upregulated in a range of cancer cell types defective in homologous recombination, and knockdown has been shown to ...

Endogenous RNA-directed DNA polymerase activity in uninfected chicken embryos.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1972
Early chicken embryos that are either positive or negative for group-specific antigens of avian leukosis viruses contained endogenous RNA-directed DNA polymerase activity. This endogenous DNA polymerase activity was not increased after mixture of soluble

Bst polymerase — a humble relative of Taq polymerase

open access: yesComputational and Structural Biotechnology Journal, 2023
DNA polymerases are a superfamily of enzymes synthesizing DNA using DNA as a template. They are essential for nucleic acid metabolism and for DNA replication and repair.

Mechanisms of PARP inhibitor resistance in cancer and insights into the DNA damage response

open access: yesGenome Medicine, 2018
Editorial summary Inhibitors of poly(ADP-ribose) polymerase (PARPi) have entered the clinic for the treatment of patients with cancers that lack homology-directed DNA repair, but drug resistance remains a clinical hurdle.

New link between the RNA polymerase II-CTD and replication stress

open access: yesMolecular & Cellular Oncology, 2021
Conflicts between transcription and replication are a major source of replication stress. Our recent findings show that proper dephosphorylation of Serine 5 in the carboxy-terminal domain (CTD) of DNA-directed RNA polymerase II subunit RPB1 is needed to ...

An efficient one-step site-directed deletion, insertion, single and multiple-site plasmid mutagenesis protocol [PDF]

open access: yes, 2012
Background: Mutagenesis plays an essential role in molecular biology and biochemistry. It has also been used in enzymology and protein science to generate proteins which are more tractable for biophysical techniques.
