KIAA0101 (PAF15) is a PCNA-associated protein expressed during S phase of the cell cycle, under the control of members of the E2F transcription factor family (Chang et al. 2013) and degraded at mitotic exit by the APC:CDH1 complex (Emanuele et al. 2011). KIAA0101 is monoubiquitinated on two lysine residues, K15 and K24, by an unknown ubiquitin ligase. Doubly monoubiquitinated KIAA0101 (PAF15) (MonoUb:K15,K24-KIAA0101) binds PCNA and promotes the switch from translesion DNA synthesis (TLS) polymerase, such as DNA polymerase eta (POLH), to replicative DNA polymerases delta (POLD) or epsilon (POLE). KIAA0101 monoubiquitination thus facilitates termination of TLS and coordinates DNA damage bypass events (Povlsen et al. 2012). UV-induced DNA damage causes removal of MonoUb:K15,K24-KIAA0101 by proteasome-mediated degradation, promoting the switch from replicative DNA polymerase complexes delta (POLD) or epsilon (POLE) to translesion DNA synthesis (TLS) polymerases, such as POLH (DNA polymerase eta) (Povlsen et al. 2012).
