- SIRT4 as a novel interactor and candidate suppressor of C-RAF kinase in MAPK signaling
This study proposed a novel extra-mitochondrial role of the tumor suppressor SIRT4 in negatively regulating the MAPK pathway by interacting with C-RAF kinase.
- A genetic screen to uncover mechanisms underlying lipid transfer protein function at membrane contact sites
A genetic screen in Drosophila photoreceptors uncovers multiple regulators of lipid transfer function and endoplasmic reticulum–plasma membrane contact sites.
- CRL4DCAF1 ubiquitin ligase regulates PLK4 protein levels to prevent premature centriole duplication
This study identifies the E3 ubiquitin ligase, CRL4DCAF1, as a new regulator of polo-like kinase 4, PLK4, protein levels in the G2 phase of the cell cycle to prevent premature duplication of centrioles.
- Correction: The pyruvate dehydrogenase complex regulates mitophagic trafficking and protein phosphorylation
Mutations in the PDC affect the phosphorylation and mitophagic trafficking of matrix proteins, through the novel regulation of associated kinases and a phosphatase. We suggest that this occurs by the direct allosteric regulation of the phosphatase and kinases by the PDC.
- The Golgi checkpoint: Golgi unlinking during G2 is necessary for spindle formation and cytokinesis
This work shows that Golgi complex disassembly during G2 is required for spindle formation and cytokinesis, thus revealing novel regulatory mechanisms that control the fidelity of mitosis.
- Genetic ablation of Immt induces a lethal disruption of the MICOS complex
A new conditional mouse model deleting Immt/MIC60 reveals the necessity of this protein in vivo and provides an important resource for future research into the mitochondrial MICOS complex.
- Interrogating endothelial barrier regulation by temporally resolved kinase network generation
This study introduces TREKING, a methodology for broadly interrogating kinases to elucidate time-resolved functional kinase signaling networks that drive endothelial barrier disruption and recovery.
- Tight regulation of a nuclear HAPSTR1-HUWE1 pathway essential for mammalian life
The recently discovered HAPSTR1 protein facilitates a nuclear quality control pathway essential for mammalian life.
- Phosphorylation of Rec8 cohesin complexes regulates mono-orientation of kinetochores in meiosis I
Phosphorylation of the Rec8 cohesin complexes plays a crucial role in establishing mono-orientation of sister kinetochores which is important for reductional division in meiosis I in fission yeast.
- Galectin-8 modulates human osteoclast activity partly through isoform-specific interactions
Galectin-8 is emerging as a key player in osteoclastic bone resorption. Explore the specific functions of its isoforms through interactome analysis, revealing intricate mechanisms of bone biology.
