RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Nucleoside‐Modified mRNA Encoding Alpha‐Galactosidase A Ameliorates Fabry Disease Phenotypes in Human IPSC‐Derived Cardiomyocytes

Advanced Science, EarlyView.
Human iPSC‐derived Fabry cardiomyocytes exhibited broad transcriptional dysregulation, apoptosis, mitochondrial dysfunction, impaired reactive oxygen species handling, altered contractility, and abnormal calcium transient decay, potentially mediated by phospholamban hyperphosphorylation.

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells

Advanced Science, EarlyView.
BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...

Asymmetric Evolution of Antennal Cell Types Underlies a Derived Ammonia‐Sensing Logic for Ecological Adaptation in Bactrocera dorsalis

Advanced Science, EarlyView.
Comparative antennal single‐nucleus transcriptomics reveals cell‐type‐dependent transcriptomic divergence in Bactrocera dorsalis, with similar structural cells but divergent sensory neurons. This neuronal diversification is associated with a distinct ammonia‐sensing pathway, linking female attraction to bird‐dropping‐associated cues with nutritional ...

Carrier‐Free Berberine/Nitidine Chloride Self‐Assembled Nanoparticles Induce Ferroptosis to Overcome Bortezomib Resistance in Multiple Myeloma

Advanced Science, EarlyView.
A schematic illustrating the fabrication process and ferroptosis‐mediated therapeutic mechanism of carrier‐free self‐assembled BBR/NC‐SAPs for overcoming bortezomib resistance in multiple myeloma. ABSTRACT Therapeutic relapse driven by bortezomib resistance represents a formidable clinical barrier in the management of multiple myeloma (MM).

RNase P RNA-mediated catalysis

Biochemical Society Transactions, 2002
The endoribonuclease RNase P is involved in the processing of tRNA precursors to generate mature 5′ termini. The catalytic activity of RNase P is associated with an RNA, RNase P RNA. A specific interaction between the 3′ end of the substrate and RNase P RNA, to form an RNase P RNA-substrate complex, is referred to as the ‘73–294-interaction’.

Roles of RNase P and Its Subunits

Trends in Genetics, 2017
Recent studies show that nuclear RNase P is linked to chromatin structure and function. Thus, variants of this ribonucleoprotein (RNP) complex bind to chromatin of small noncoding RNA genes; integrate into initiation complexes of RNA polymerase (Pol) III; repress histone H3.3 nucleosome deposition; control tRNA and PIWI-interacting RNA (piRNA) gene ...

A novel protein shared by RNase MRP and RNase P

RNA (New York, N.Y.), 1997
We have isolated suppressors of the temperature-sensitive rRNA processing mutation rrp2-2 in Saccharomyces cerevisiae. A class of extragenic suppressors was mapped to the YBR257w reading frame in the right arm of Chromosome II. Characterization of this gene, renamed POP4, shows that the gene product is necessary both for normal 5.8S rRNA processing and

Definition of the Th/ To ribonucleoprotein by RNase P and RNase MRP

Molecular Biology Reports, 1993
We show that the Th/To ribonucleoprotein is defined by (i) the co-immunoprecipitation of two RNAs, (ii) the co-immunoprecipitation of four major polypeptides and (iii) the quantitative immune recognition of both RNase P and RNase MRP. No serum was found that recognizes either one of these two enzymes exclusively.

Eukaryote RNase P and RNase MRP

2009
Ribonuclease P (RNase P) is an essential endonuclease that catalyzes the cleavage of the 5′ leader sequence from precursor tRNAs (pre-tRNAs). Most forms of RNase P are ribonucleoproteins and the bacterial enzyme possesses a single catalytic RNA and one small protein.
