Mitochondrial RNA editing in Trypanoplasma borreli: New tools, new revelations

Computational and Structural Biotechnology Journal, 2022
The kinetoplastids are unicellular flagellates that derive their name from the ‘kinetoplast’, a region within their single mitochondrion harboring its organellar genome of high DNA content, called kinetoplast (k) DNA.

PlmCas12e (CasX2) cleavage of CCR5: impact of guide RNA spacer length and PAM sequence on cleavage activity

RNA Biology, 2023
Gene editing using CRISPR/Cas (clustered regularly interspaced palindromic repeats/CRISPR-associated) is under development as a therapeutic tool for the modification of genes in eukaryotic cells.

Crosstalk between CRISPR-Cas9 and the human transcriptome

Nature Communications, 2022
The off-target effects of CRISPR-Cas9 are thought to be mediated by its cognate guide RNA. Here the authors show that Cas9 independently interacts with the human transcriptome, correlating with elevated RNA editing even under guide RNA co-expression.

Characterization of a Programmable Argonaute Nuclease from the Mesophilic Bacterium Rummeliibacillus suwonensis

Biomolecules, 2022
Prokaryotic Argonautes (pAgos) from mesophilic bacteria are attracting increasing attention for their genome editing potential. So far, it has been reported that KmAgo from Kurthia massiliensis can utilize DNA and RNA guide of any sequence to effectively

Lipid nanoparticle-mediated codelivery of Cas9 mRNA and single-guide RNA achieves liver-specific in vivo genome editing of Angptl3

Proceedings of the National Academy of Sciences of the United States of America, 2021
Significance Genome editing technologies enable the permanent repair of disease-causing genetic mutations. However, the application of this technology has been limited by the technical challenge of achieving safe, effective, and specific in vivo delivery

Transcriptome-wide Cas13 guide RNA design for model organisms and viral RNA pathogens

Cell Genomics, 2021
Summary: The recent characterization of RNA-targeting CRISPR nucleases has enabled diverse transcriptome engineering and screening applications that depend crucially on prediction and selection of optimized CRISPR guide RNAs (gRNAs).

Structural basis for sequence-specific recognition of guide and target strands by the Archaeoglobus fulgidus Argonaute protein

Scientific Reports, 2023
Argonaute (Ago) proteins are found in all three domains of life. The best-characterized group is eukaryotic Argonautes (eAgos). Being the structural core of RNA interference machinery, they use guide RNA molecules for RNA targeting.

Functional organization of box C/D RNA-guided RNA methyltransferase [PDF]

, 2020
Box C/D RNA protein complexes (RNPs) catalyze site-specific 2'-O-methylation of RNA with specificity determined by guide RNAs. In eukaryotic C/D RNP, the paralogous Nop58 and Nop56 proteins specifically associate with terminal C/D and internal C'/D ...
