PMID: 33302237
Psychoneuroendocrinology. 2021 Feb;124:105097. doi: 10.1016/j.psyneuen.2020.105097. Epub 2020 Dec 01.

Major depressive disorder is a common debilitating mental health problem that represents one of the leading causes of disability. Up to date, the therapeutic targets and approaches are still limited. Adult hippocampal neurogenesis (AHN) has been proposed as a...

RAD51 supports DMC1 by inhibiting the SMC5/6 complex during meiosis.

The Plant cell

Chen H, He C, Wang C, Wang X, Ruan F, Yan J, Yin P, Wang Y, Yan S.
PMID: 34009315
Plant Cell. 2021 Aug 31;33(8):2869-2882. doi: 10.1093/plcell/koab136.

Meiosis is a fundamental process for sexual reproduction in most eukaryotes and the evolutionarily conserved recombinases RADiation sensitive51 (RAD51) and Disrupted Meiotic cDNA1 (DMC1) are essential for meiosis and thus fertility. The mitotic function of RAD51 is clear, but...

Salmonella Genomic Island 1 requires a self-encoded small RNA for mobilization.

Molecular microbiology

Nagy I, Szabó M, Hegyi A, Kiss J.
PMID: 34784078
Mol Microbiol. 2021 Dec;116(6):1533-1551. doi: 10.1111/mmi.14846. Epub 2021 Nov 25.

The SGI1-family elements that are specifically mobilized by the IncA- and IncC-family plasmids are important vehicles of antibiotic resistance among enteric bacteria. Although SGI1 exploits many plasmid-derived conjugation and regulatory functions, the basic mobilization module of the island is...

Virus and Potential Host Microbes from Viral-Enriched Metagenomic Characterization in the High-Altitude Wetland, Salar de Huasco, Chile.

Microorganisms

Eissler Y, Dorador C, Kieft B, Molina V, Hengst M.
PMID: 32698305
Microorganisms. 2020 Jul 20;8(7). doi: 10.3390/microorganisms8071077.

Salar de Huasco is a wetland in the Andes mountains, located 3800 m above sea level at the Chilean Altiplano. Here we present a study aimed at characterizing the viral fraction and the microbial communities through metagenomic analysis. Two...

Sources of off-target expression from recombinase-dependent AAV vectors and mitigation with cross-over insensitive ATG-out vectors.

Proceedings of the National Academy of Sciences of the United States of America

Fischer KB, Collins HK, Callaway EM.
PMID: 31843925
Proc Natl Acad Sci U S A. 2019 Dec 16; doi: 10.1073/pnas.1915974116. Epub 2019 Dec 16.

In combination with transgenic mouse lines expressing Cre or Flp recombinases in defined cell types, recombinase-dependent adeno-associated viruses (AAVs) have become the tool of choice for localized cell-type-targeted gene expression. Unfortunately, applications of this technique when expressing highly sensitive...

Recombining DNA by protein swivels.

Structure (London, England : 1993)

Johnson RC, McLean MM.
PMID: 21645847
Structure. 2011 Jun 08;19(6):751-3. doi: 10.1016/j.str.2011.05.007.

Two new reports on serine recombinases, one of a crystal snapshot in an alternate rotational conformer poised for DNA cleavage (Keenholtz et al., 2011), and a second employing single-DNA molecule approaches (Bai et al., 2011), provide strong support for...

Thermodynamic Properties of Water Molecules at a Protein-Protein Interaction Surface.

Journal of chemical theory and computation

Huggins DJ, Marsh M, Payne MC.
PMID: 24554921
J Chem Theory Comput. 2011 Nov 08;7(11):3514-3522. doi: 10.1021/ct200465z. Epub 2011 Sep 20.

Protein-protein interactions (PPIs) have been identified as a vital regulator of cellular pathways and networks. However, the determinants that control binding affinity and specificity at protein surfaces are incompletely characterized and thus unable to be exploited for the purpose...

Conditional mutagenesis of the genome using site-specific DNA recombination.

CSH protocols

Ohtsubo K, Marth JD.
PMID: 21357131
CSH Protoc. 2007 Jul 01;2007:pdb.top12. doi: 10.1101/pdb.top12.

INTRODUCTIONAltering the genome of intact cells and organisms by site-specific DNA recombination has become an important gene-transfer methodology. DNA modifications produced by gene transfer and homologous recombination are typically static once integrated among target cell chromosomes. In contrast, the...

Genetic methods to identify and manipulate newly born neurons in the adult brain.

Frontiers in neuroscience

Front Neurosci. 2011 May 02;5:64. doi: 10.3389/fnins.2011.00064. eCollection 2011.

Although mammalian neurogenesis is mostly completed by the perinatal period, new neurons are continuously generated in the subventricular zone of the lateral ventricle and the subgranular zone of the hippocampal dentate gyrus. Since the discovery of adult neurogenesis, many...

Filamentous phages of Ralstonia solanacearum: double-edged swords for pathogenic bacteria.

Frontiers in microbiology

Front Microbiol. 2013 Nov 04;4:325. doi: 10.3389/fmicb.2013.00325. eCollection 2013.

Some phages from genus Inovirus use host or bacteriophage-encoded site-specific integrases or recombinases establish a prophage state. During integration or excision, a superinfective form can be produced. The three states (free, prophage, and superinfective) of such phages exert different...

Two different evolutionary lines of filamentous phages in Ralstonia solanacearum: their effects on bacterial virulence.

Front Genet. 2015 Jun 18;6:217. doi: 10.3389/fgene.2015.00217. eCollection 2015.

The integration and excision of various filamentous phage genomes into and out of their host chromosomes occurs by site-specific recombination. The mechanisms proposed for these events include reactions mediated by phage-encoded recombinases and host recombination systems. Site-specific integration of...

Sequence analysis of tyrosine recombinases allows annotation of mobile genetic elements in prokaryotic genomes.

Mobile genetic elements (MGEs) sequester and mobilize antibiotic resistance genes across bacterial genomes. Efficient and reliable identification of such elements is necessary to follow resistance spreading. However, automated tools for MGE identification are missing. Tyrosine recombinase (YR) proteins drive...
