Structural and functional investigations identify a structural unit for ephaptic coupling in the heart, and provide the mechanistic basis for a novel strategy for the treatment of arrhythmias.
The exon junction complex regulates the cell polarity determinant Discs large 1, which acts independently from its role in cell polarity to protect Dishevelled protein from lysosomal degradation in Wingless/Wnt signaling.
The crystal structure of human Holliday junction resolvase GEN1 in complex with DNA reveals a conserved chromodomain as an additional DNA-anchoring point that opens new perspectives for enzyme regulation.
Genetic data revealed existing drugs that could be repurposed to improve lung function, with evidence that compounds which control blood glucose could be particularly useful for respiratory impairment.
Junction Mapper is a powerful new semi-automated software that provides a fingerprint of cell–cell contact morphometry and receptor density alterations.
Deposition of the exon junction complex is thought to be the missing link between pre-mRNA splicing and translation in multicellular organisms, but no evidence of such deposition has been found in Drosophila.
Developing long bones contain distinct mesenchymal stem-cell populations derived from mesoderm and neural crest, which have specialized functions in skeleton formation and the establishment of the hematopoietic stem-cell niche, respectively.
As the first fully genetically encoded method, PARIS allows cell-specific, long-term, repeated measurements of gap junctional coupling with high spatiotemporal resolution, facilitating its study in both health and disease.
