    Ongoing repair of migration-coupled DNA damage allows planarian adult stem cells to reach wound sites

    Sounak Sahu et al.
    Adult stem cells acquire increased DNA damage as they migrate to a wound site and require active DNA repair mechanisms for normal migration.

    HPF1 and nucleosomes mediate a dramatic switch in activity of PARP1 from polymerase to hydrolase

    Johannes Rudolph et al.
    The polymerase activity of PARP1 is converted to hydrolase activity upon binding of Histone Parylation Factor 1 (HPF1) with nucleosome activators.

    NAD+ enhances ribitol and ribose rescue of α-dystroglycan functional glycosylation in human FKRP-mutant myotubes

    Carolina Ortiz-Cordero et al.
    The combined use of NAD+ with ribitol or ribose potentiates the rescue of α-dystroglycan functional glycosylation in FKRP-mutant patient-specific iPSC-derived myotubes, representing potential novel treatments for FKRP muscular dystrophies.

    Chemical genetics and proteome-wide site mapping reveal cysteine MARylation by PARP-7 on immune-relevant protein targets

    Kelsie M Rodriguez et al.
    A combined chemical genetics, proximity labeling, and ADP-ribose site mapping approach shows that PARP-7 mono-ADP-ribosylates immune-relevant proteins on cysteine amino acids.

    Identification of PARP-7 substrates reveals a role for MARylation in microtubule control in ovarian cancer cells

    Lavanya H Palavalli Parsons et al.
    PARP-7 is a mono(ADP-ribosyl) transferase that directs an extensive ADP-ribosylated proteome to control microtubule stability, and regulate ovarian cancer cell growth and motility.

    ARL3 activation requires the co-GEF BART and effector-mediated turnover

    Yasmin ElMaghloob et al.
    BART is a co-GEF for ARL3 and maintains the active ARL3-GTP until it is recycled by ARL3 effectors.

    Structural basis for effector transmembrane domain recognition by type VI secretion system chaperones

    Shehryar Ahmad et al.
    A widespread family of chaperones functions to stabilize membrane protein effectors by mimicking transmembrane helical environments and promotes effector export by the bacterial type VI secretion system.

    PARP1 inhibitors trigger innate immunity via PARP1 trapping-induced DNA damage response

    Chiho Kim et al.
    Identification of PARP1 trapping as the major contributor of PARP1 inhibitor-induced innate immune response.

    The manifold actions of signaling peptides on subcellular dynamics of a receptor specify stomatal cell fate

    Xingyun Qi et al.
    A binary cell fate decision to be or not to be stomata is regulated by multiple peptide ligands, each triggering a unique subcellular dynamics of their shared receptor.

    Synergy between SIRT1 and SIRT6 helps recognize DNA breaks and potentiates the DNA damage response and repair in humans and mice

    Fanbiao Meng et al.
    SIRT1 deacetylates SIRT6 at K33 to facilitate DNA double-strand breaks-recognition, subsequent expansion and local chromatin remodeling.
