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

    Lavanya H Palavalli Parsons, Sridevi Challa ... W Lee Kraus
    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.
