UBC13 is an E2 ubiquitin conjugating enzyme that can form a heterodimer with Mms2 to function as a part of the Translesion DNA Synthesis Pathway (TLS). When bound to Mms2, Ubc13 will polyubiquinate PCNA, proliferating cell nuclear antigen, a sliding clamp protein at the DNA transcription fork. UBC13-MMS2 functions to polyubiquinate PCNA following the initial monoubiquitination by Rad6-Rad18(another E2 complex).
