DNA polymerase kappa supports genome repair in cultured neurons

In mouse and human neurons, depleting POLK reduced repair-associated DNA synthesis and induced senescence-like stress, while augmenting POLK lowered DNA damage markers.In mouse and human neurons, depleting POLK reduced repair-associated DNA synthesis and induced senescence-like stress, while augmenting POLK lowered DNA damage markers.
