reach
"POH1 activity associated with the proteasome results in cleavage of K63 chains at damage sites, and limits the accumulation of 53BP1 at DSBs."

reach
"Reduced DNA repair in RNF8-, RNF168- or 53BP1 depleted cells, in which no 53BP1 IRIF form, could be countered by co-depletion of POH1, which restored both repair and 53BP1 IRIF."

reach
"USP44, USP17L2/DUB3, USP11, ZUFSP and POH1 loss promotes the excessive spreading of Ub at DSBs and concomitant excessive accumulation of 53BP1 [57–65]."
