    Repression of interrupted and intact rDNA by the SUMO pathway in Drosophila melanogaster

    Yicheng Luo et al.
    SUMO-dependent pathway is responsible for selective repression of damaged rDNA and silencing of intact surplus units revealing an epigenetic mechanism that controls the differential expression of identical sequences in the same cell.

    Wss1 metalloprotease partners with Cdc48/Doa1 in processing genotoxic SUMO conjugates

    Maxim Y Balakirev et al.
    Wss1 is both a metalloprotease and SUMO ligase found in association with Cdc48 and Doa1 and accumulating in the vacuole upon DNA damage.

    Analysis of SUMO1-conjugation at synapses

    James A Daniel et al.
    Analyses using His6-HA-SUMO1 and SUMO1 KO mice indicate that SUMO1 modification of synaptic proteins is either absent or cannot be detected in brain and cultured neurons.

    Defective RNA polymerase III is negatively regulated by the SUMO-Ubiquitin-Cdc48 pathway

    Zheng Wang et al.
    The SUMO-Ub-Cdc48 pathway is a novel regulatory mechanism of Pol III and a potential therapeutic target for Pol III-related human diseases.

    SUMOylation of NaV1.2 channels mediates the early response to acute hypoxia in central neurons

    Leigh D Plant et al.
    The immediate response of the brain to a sudden, harmful drop in oxygen supply is the addition of SUMO proteins to sodium ion channels in neurons, increasing their activity.

    A gene-expression screen identifies a non-toxic sumoylation inhibitor that mimics SUMO-less human LRH-1 in liver

    Miyuki Suzawa et al.
    The FDA-approved compound and plant extract tannic acid is a non-toxic chemical tool for modulating sumoylation in multiple platforms.

    Allosteric activation of SENP1 by SUMO1 β-grasp domain involves a dock-and-coalesce mechanism

    Jingjing Guo, Huan-Xiang Zhou
    Simulations of molecular dynamics suggest how the binding of the β-grasp domain of SUMO1 induces conformational and dynamic effects to activate SENP1.

    SUMO peptidase ULP-4 regulates mitochondrial UPR-mediated innate immunity and lifespan extension

    Kaiyu Gao et al.
    SUMOylation regulates mitochondrial UPR signaling through modulation of transcription factors DVE-1 and ATFS-1.

    The transcriptomic response of cells to a drug combination is more than the sum of the responses to the monotherapies

    Jennifer EL Diaz et al.
    The transcriptomic profiles of the constituent monotherapies of synergistic drug pairs tend to be correlated and result in novel gene expression in the combinations.
