Tyrosine site-specific recombinases (SSRs) represent a versatile genome editing tool with considerable therapeutic potential. Recent developments to engineer and evolve SSRs into heterotetramers to improve target site flexibility signified a critical step towards their broad utility in genome editing....

A toolbox for conditional control of gene expression in apicomplexan parasites.

Molecular microbiology

Briquet S, Gissot M, Silvie O.
PMID: 34564906
Mol Microbiol. 2021 Sep 26; doi: 10.1111/mmi.14821. Epub 2021 Sep 26.

Apicomplexan parasites encompass diverse pathogens for humans and animals, including the causative agents of malaria and toxoplasmosis, Plasmodium spp. and Toxoplasma gondii. Genetic manipulation of these parasites has become central to explore parasite biology, unravel gene function and identify...

Elucidating Recombination Mediator Function Using Biophysical Tools.

Biology

PMID: 33916151
Biology (Basel). 2021 Apr 01;10(4). doi: 10.3390/biology10040288.

The recombination mediator proteins (RMPs) are ubiquitous and play a crucial role in genome stability. RMPs facilitate the loading of recombinases like RecA onto single-stranded (ss) DNA coated by single-strand binding proteins like SSB. Despite sharing a common function,...

Mechanisms of distinctive mismatch tolerance between Rad51 and Dmc1 in homologous recombination.

Nucleic acids research

Xu J, Zhao L, Peng S, Chu H, Liang R, Tian M, Connell PP, Li G, Chen C, Wang HW.
PMID: 34871438
Nucleic Acids Res. 2021 Dec 16;49(22):13135-13149. doi: 10.1093/nar/gkab1141.

Homologous recombination (HR) is a primary DNA double-strand breaks (DSBs) repair mechanism. The recombinases Rad51 and Dmc1 are highly conserved in the RecA family; Rad51 is mainly responsible for DNA repair in somatic cells during mitosis while Dmc1 only...

Virally encoded connectivity transgenic overlay RNA sequencing (VECTORseq) defines projection neurons involved in sensorimotor integration.

Cell reports

Cheung V, Chung P, Bjorni M, Shvareva VA, Lopez YC, Feinberg EH.
PMID: 34936877
Cell Rep. 2021 Dec 21;37(12):110131. doi: 10.1016/j.celrep.2021.110131.

Behavior arises from concerted activity throughout the brain. Consequently, a major focus of modern neuroscience is defining the physiology and behavioral roles of projection neurons linking different brain areas. Single-cell RNA sequencing has facilitated these efforts by revealing molecular...

Bacteriophage-encoded single strand annealing proteins (SSAPs) are recombinases which can substitute the classical, bacterial RecA and manage the DNA metabolism at different steps of phage propagation. SSAPs have been shown to efficiently promote recombination between short and rather divergent...

Helicase-like functions in phosphate loop containing beta-alpha polypeptides.

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

Vyas P, Trofimyuk O, Longo LM, Deshmukh FK, Sharon M, Tawfik DS.
PMID: 33846247
Proc Natl Acad Sci U S A. 2021 Apr 20;118(16). doi: 10.1073/pnas.2016131118.

The P-loop Walker A motif underlies hundreds of essential enzyme families that bind nucleotide triphosphates (NTPs) and mediate phosphoryl transfer (P-loop NTPases), including the earliest DNA/RNA helicases, translocases, and recombinases. What were the primordial precursors of these enzymes? Could...

Robust Cre recombinase activity in the biotrophic smut fungus Ustilago maydis enables efficient conditional null mutants in planta.

Genetics. 2021 Sep 17; doi: 10.1093/genetics/iyab152. Epub 2021 Sep 17.

Site-specific recombinases have been used in higher eukaryotes, especially in animals, for a broad range of applications, including chromosomal translocations, large deletions, site-specific integration, and tissue-specific as well as conditional knock-outs. The application of site-specific recombination has also been...

Inner workings of RAG recombinase and its specialization for adaptive immunity.

Current opinion in structural biology

Curr Opin Struct Biol. 2021 Dec;71:79-86. doi: 10.1016/j.sbi.2021.05.014. Epub 2021 Jul 07.

RAG1/2 (RAG) is an RNH-type DNA recombinase specially evolved to initiate V(D)J gene rearrangement for generating the adaptive immune response in jawed vertebrates. After decades of frustration with little mechanistic understanding of RAG, the crystal structure of mouse RAG...

Precisely deciphering the cellular plasticity in vivo is essential in understanding many key biological processes. Site-specific recombinases are genetic tools used for in vivo lineage tracing and gene manipulation. Conventional Cre-loxP, Dre-rox, and Flp-frt technologies form the orthogonal recombination...
