POLQ mediated end-joining promotes DNA damage tolerance in neuroblastoma

Translational Oncology
Segmental chromosomal alterations, including 11q deletion and 17q gain, are the strongest predictors of pediatric neuroblastoma relapse. These alterations result from unbalanced translocations linked to erroneous DNA repair.

Mutational phospho-mimicry reveals a regulatory role for the XRCC4 and XLF C-terminal tails in modulating DNA bridging during classical non-homologous end joining

eLife, 2017
XRCC4 and DNA Ligase 4 (LIG4) form a tight complex that provides DNA ligase activity for classical non-homologous end joining (the predominant DNA double-strand break repair pathway in higher eukaryotes) and is stimulated by XLF.

Characterization of a temperature-sensitive DNA ligase from Escherichia coli [PDF]

, 2004
DNA ligases are essential enzymes in cells due to their ability to join DNA strand breaks formed during DNA replication. Several temperature-sensitive mutant strains of Escherichia coli, including strain GR501, have been described which can be ...

SmallTalk: a novel small‐sized fusion tag for peptide expression and purification

FEBS Open Bio, EarlyView.
The SmallTalk fusion tag allows for the efficient expression and purification of soluble recombinant proteins or peptides in Escherichia coli. Testing with SmallTalk‐GFP confirmed that the proteins were soluble and folded correctly, while SmallTalk‐Bin1b maintained its antimicrobial activity against various bacterial isolates. This streamlined workflow

Arabidopsis DNA polymerase lambda mutant is mildly sensitive to DNA double strand breaks but defective in integration ofa transgene.

Frontiers in Plant Science, 2015
The DNA double-strand break (DSB) is a critical type of damage, and can be induced by both endogenous sources (e.g. errors of oxidative metabolism, transposable elements, programmed meiotic breaks, or perturbation of the DNA replication fork) and ...

Smc5/6: a link between DNA repair and unidirectional replication? [PDF]

, 2008
Of the three structural maintenance of chromosome (SMC) complexes, two directly regulate chromosome dynamics. The third, Smc5/6, functions mainly in homologous recombination and in completing DNA replication.

DNA Ligases: Progress and Prospects [PDF]

Journal of Biological Chemistry, 2009
DNA ligases seal 5'-PO4 and 3'-OH polynucleotide ends via three nucleotidyl transfer steps involving ligase-adenylate and DNA-adenylate intermediates. DNA ligases are essential guardians of genomic integrity, and ligase dysfunction underlies human genetic disease syndromes.

BMI‐1 modulation and trafficking during M phase in diffuse intrinsic pontine glioma

FEBS Open Bio, EarlyView.
The schematic illustrates BMI‐1 phosphorylation during M phase, which triggers its translocation from the nucleus to the cytoplasm. In cycling cells, BMI‐1 functions within the PRC1 complex to mediate H2A K119 monoubiquitination. Following PTC596‐induced M phase arrest, phosphorylated BMI‐1 dissociates from PRC1 and is exported to the cytoplasm via its

Efficient assembly of very short oligonucleotides using T4 DNA Ligase

BMC Research Notes, 2010
Background In principle, a pre-constructed library of all possible short oligonucleotides could be used to construct many distinct gene sequences. In order to assess the feasibility of such an approach, we characterized T4 DNA Ligase activity on short ...

Identification of novel components of Trypanosoma brucei editosomes [PDF]

, 2003
The editosome is a multiprotein complex that catalyzes the insertion and deletion of uridylates that occurs during RNA editing in trypanosomatids. We report the identification of nine novel editosome proteins in Trypanosoma brucei.
