    SWI/SNF senses carbon starvation with a pH-sensitive low-complexity sequence

    J Ignacio Gutierrez, Gregory P Brittingham ... Liam J Holt
    A combination of single-cell analysis, genomics, and simulations shows that a glutamine-rich low-complexity sequence in the SWI/SNF chromatin remodeling complex senses transient intracellular acidification as a signal for cells to switch their global transcriptional program.

    Snf1/AMPK fine-tunes TORC1 signaling in response to glucose starvation

    Marco Caligaris, Raffaele Nicastro ... Claudio De Virgilio
    Discovery of new Snf1/AMPK targets in the TORC1 pathway highlights the complex, multilayered crosstalk between major signaling pathways in the regulation of nutrient deprivation sensing.

    Crystal structure of the full Swi2/Snf2 remodeler Mot1 in the resting state

    Agata Butryn, Stephan Woike ... Karl-Peter Hopfner
    The structure of the entire Mot1 Swi2/Snf2 protein uncovers an unexpected auto-inhibited resting state activated by substrate binding, and suggests a DNA pulling mechanism of TBP displacement.

    NF1 regulates mesenchymal glioblastoma plasticity and aggressiveness through the AP-1 transcription factor FOSL1

    Carolina Marques, Thomas Unterkircher ... Massimo Squatrito
    Neurofibromatosis type 1 gene (NF1) signaling is causally linked to the acquisition of a mesenchymal gene expression program in gliomas through the regulation of the AP-1 transcription factor FOSL1.

    OXPHOS deficiencies affect peroxisome proliferation by downregulating genes controlled by the SNF1 signaling pathway

    Jean-Claude Farre, Krypton Carolino ... Suresh Subramani
    The emerging importance of interorganellar communication is demonstrated by documentation of a feedback loop wherein peroxisome-generated metabolites affect mitochondrial ATP production and peroxisomal functions via signaling pathways requiring transmission of signals also through the cytosol and the nucleus.

    In vivo analysis reveals that ATP-hydrolysis couples remodeling to SWI/SNF release from chromatin

    Ben C Tilly, Gillian E Chalkley ... C Peter Verrijzer
    Visualization of BRM remodelers engaging their endogenous genomic targets revealed highly transient and dynamic interactions with chromatin, which are fueled by ATP-hydrolysis.

    Inositol polyphosphate multikinase physically binds to the SWI/SNF complex and modulates BRG1 occupancy in mouse embryonic stem cells

    Jiyoon Beon, Sungwook Han ... Daeyoup Lee
    Inositol polyphosphate multikinase physically binds to the core subunits of SWI/SNF complex and plays an important role in regulating BRG1 occupancy and BRG-mediated chromatin accessibility in mouse embryonic stem cells.

    Structural basis for activation, assembly and membrane binding of ESCRT-III Snf7 filaments

    Shaogeng Tang, W Mike Henne ... Scott D Emr
    Snf7 crystal structures reveal the mechanisms of ESCRT-III activation and polymerization into membrane-remodeling filaments.

    Synergy between loss of NF1 and overexpression of MYCN in neuroblastoma is mediated by the GAP-related domain

    Shuning He, Marc R Mansour ... A Thomas Look
    A zebrafish model of neuroblastoma reveals that the tumor suppressor NF1 uses different mechanisms to suppress malignant transformation and to down-modulate normal neural crest cell growth during embryogenesis.
