Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe

FEBS Open Bio, EarlyView.
Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Emerging functions of mammalian mitochondrial fusion and fission [PDF]

, 2005
Mitochondria provide a myriad of services to the cell, including energy production, calcium buffering and regulation of apoptosis. How these diverse functions are coordinated among the hundreds of mitochondria in a given cell is largely unknown, but is ...

MDP25‐VDAC3 Complex Orchestrates Actin Remodeling and Mitochondrial Dynamics to Modulate Innate Immunity in Arabidopsis

Advanced Science, EarlyView.
This study reveals that actin remodeling regulates mitochondrial elongation as a defense strategy in plants. Flagellin perception induces fusion‐dependent elongation, supported by cortical actin bundles, to repair damage and boost ATP and ROS production.

Mitochondrial dynamics–fusion, fission, movement, and mitophagy–in neurodegenerative diseases [PDF]

, 2009
Neurons are metabolically active cells with high energy demands at locations distant from the cell body. As a result, these cells are particularly dependent on mitochondrial function, as reflected by the observation that diseases of mitochondrial ...

A Non‐Mitophagy Activity of BNIP3L/NIX in Amygdala Glutamatergic Neurons is Essential for Contextual Fear Memory Formation

Advanced Science, EarlyView.
Contextual fear conditioning induces BNIP3L‐dependent mitochondrial fission in glutamatergic neurons of the BLA, independently of mitophagy. Loss of BNIP3L elevates Drp1Ser637 phosphorylation, thereby suppressing mitochondrial fission, compromising ATP production, and attenuating excitatory synaptic transmission.

Role of the Schizosaccharomyces pombe F-box DNA helicase in processing recombination intermediates. [PDF]

, 2005
In an effort to identify novel genes involved in recombination repair, we isolated fission yeast Schizosaccharomyces pombe mutants sensitive to methyl methanesulfonate (MMS) and a synthetic lethal with rad2.

Identification of Fis1 Interactors in Toxoplasma gondii Reveals a Novel Protein Required for Peripheral Distribution of the Mitochondrion [PDF]

, 2020
Toxoplasma gondii’s single mitochondrion is very dynamic and undergoes morphological changes throughout the parasite’s life cycle. During parasite division, the mitochondrion elongates, enters the daughter cells just prior to cytokinesis, and undergoes ...
