Structure‐Guided Engineering of a Cas12i Nuclease Unlocks Near‐PAMless Genome Editing

open access: yesAdvanced Science, EarlyView.
CRISPR‐Cas nucleases are limited by PAM requirements, restricting genome accessibility. Structure‐guided engineering of the compact Cas12i nuclease SF01 produced three variants with near‐PAMless, enabling efficient editing at diverse 5'‐NNTN‐3' sites. These nucleases expand the editable portion of the human genome more than fourfold, enabling efficient

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

open access: yesAdvanced Science, EarlyView.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

Antibiotics and RNase P

open access: yesAntibiotics, 2016
RNase P is an essential endonuclease in tRNA biogenesis, which generates the mature 5′-termini of tRNAs. Most forms of RNase P are ribonucleoproteins, i.e., they consist of an essential RNA and protein subunits.

TOPK Inhibition Promotes Anti‐Tumor Immunity Via eIF4F Complex Mediated STAT1 Translation in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies TOPK as a dual‐function target in gastric cancer: it drives tumor cell proliferation and migration, and under IFN‐γ stimulation, phosphorylates eIF4F complex component eIF4A1 to enhance STAT1 mRNA translation, thereby promoting PD‐L1/IDO1‐mediated tumor immunometabolic evasion.

Topological barrier to Cas12a activation by circular DNA nanostructures facilitates autocatalysis and transforms DNA/RNA sensing

open access: yesNature Communications
Control of CRISPR/Cas12a trans-cleavage is crucial for biosensor development. Here, we show that small circular DNA nanostructures which partially match guide RNA sequences only minimally activate Cas12a ribonucleoproteins.

Synthetic Lethal Therapy Based on Dimorphism for Systemic Infection of Drug‐Resistant Candida albicans

open access: yesAdvanced Science, EarlyView.
To tackle the alarming mortality rate linked to Candida albicans infections, a synthetic lethal strategy precisely aimed at the two distinct forms of this fungus: yeast and hyphae is formulated. Ultimately, through the innovative use of macrophage membranes for drug delivery, the effectiveness of this strategy is substantially boosted while ...

Chemical Proteomics Identifies Ketogenesis‐Mediated Cysteine Modifications Regulating Redox Function

open access: yesAngewandte Chemie, EarlyView.
Herein, we report ketone body induce cysteine modifications beyond lysine acylation, as revealed by integrating chemical proteomics with open‐search methods. Among the modifications, cysteine crotonation (Ccr) was chemically validated by endogenous peptide‐based co‐elution assays.

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

open access: yesAdvanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in
