CC -!- FUNCTION: Involved in UV protection and mutation. Poorly processive, CC error-prone DNA polymerase involved in translesion repair CC (PubMed:10801133). Essential for induced (or SOS) mutagenesis. Able to CC replicate DNA across DNA lesions (thymine photodimers and abasic sites, CC called translesion synthesis) in the presence of activated RecA; CC efficiency is maximal in the presence of the beta sliding-clamp and CC clamp-loading complex of DNA polymerase III plus single-stranded CC binding protein (SSB) (PubMed:10801133). RecA and to a lesser extent CC the beta clamp-complex may target Pol V to replication complexes CC stalled at DNA template lesions (PubMed:10801133). CC {ECO:0000269|PubMed:10801133}. CC -!- INTERACTION: CC P0AG11; P0AG11: umuD; NbExp=6; IntAct=EBI-1122622, EBI-1122622; CC PRO_0000027305; P04152: umuC; NbExp=7; IntAct=EBI-25426537, EBI-1119849; CC -!- INDUCTION: Repressed by LexA, induced by DNA damage (PubMed:10760155). CC Induced 1.5-fold by hydroxyurea (PubMed:20005847). CC {ECO:0000269|PubMed:10760155, ECO:0000269|PubMed:20005847}. CC -!- SIMILARITY: Belongs to the peptidase S24 family. {ECO:0000305}.
