Microhomology-mediated end joining induces hypermutagenesis at breakpoint junctions. [PDF]
Microhomology (MH) flanking a DNA double-strand break (DSB) drives chromosomal rearrangements but its role in mutagenesis has not yet been analyzed. Here we determined the mutation frequency of a URA3 reporter gene placed at multiple locations distal to ...

Robust activation of microhomology-mediated end joining for precision gene editing applications. [PDF]
One key problem in precision genome editing is the unpredictable plurality of sequence outcomes at the site of targeted DNA double stranded breaks (DSBs).

Recurrent deletions in clonal hematopoiesis are driven by microhomology-mediated end joining [PDF]
The mutational mechanisms that produce insertions and deletions that lead to clonal hematopoiesis are poorly understood. Here the authors show evidence that frequent deletions that are relevant to myeloid malignancies could be produced by PARP1-dependent

Translesion synthesis and microhomology-mediated end-joining repair in trypanosomatids. [PDF]
Trypanosomatid parasites and the diseases they cause affect more than 30 million people annually worldwide. To develop treatments for these diseases, it is critical to understand how trypanosomatid biology protects the parasite, so that these mechanisms ...

Structural basis for Polθ-helicase DNA binding and microhomology-mediated end-joining [PDF]
DNA double-strand breaks (DSBs) present a critical threat to genomic integrity, often precipitating genomic instability and oncogenesis. Repair of DSBs predominantly occurs through homologous recombination (HR) and non-homologous end joining (NHEJ).

Polθ promotes the repair of 5′-DNA-protein crosslinks by microhomology-mediated end-joining [PDF]
Summary: DNA polymerase θ (Polθ) confers resistance to chemotherapy agents that cause DNA-protein crosslinks (DPCs) at double-strand breaks (DSBs), such as topoisomerase inhibitors. This suggests Polθ might facilitate DPC repair by microhomology-mediated

Molecular basis of microhomology-mediated end-joining by purified full-length Polθ [PDF]
DNA polymerase θ is a polymerase-helicase essential for microhomology-mediated end-joining (MMEJ) or alternative end-joining of DNA. Here the authors use biochemical and biophysical methods to reveal how full-length human DNA polymerase θ performs MMEJ ...

In vivo and in vitro knockout system labelled using fluorescent protein via microhomology-mediated end joining [PDF]
This study provides a new method that enables the labelling of knockout cells with fluorescent protein through microhomology-mediated end joining (MMEJ)–based knock-in. Gene knockout is important for understanding gene function and genetic disorders. The

Optimizing CRISPR precision in mouse embryos via microhomology-mediated end joining-dominant targeting [PDF]
CRISPR/Cas9 technology enables efficient gene editing in mice, but its reliance on non-homologous end joining often leads to unpredictable and mosaic mutations in founder (F0) animals.

Endogenous CRISPR-assisted microhomology-mediated end joining enables rapid genome editing in Zymomonas mobilis [PDF]
Background Zymomonas mobilis is a natural ethanologen with many desirable characteristics, making it an ideal platform for future biorefineries. Recently, an endogenous CRISPR-based genome editing tool has been developed for this species.
