CC -!- FUNCTION: Involved in UV protection and mutation. Poorly CC processive, error-prone DNA polymerase involved in translesion CC repair (PubMed:10801133). Essential for induced (or SOS) CC mutagenesis. Able to replicate DNA across DNA lesions (thymine CC photodimers and abasic sites, called translesion synthesis) in the CC presence of activated RecA; efficiency is maximal in the presence CC of the beta sliding-clamp and clamp-loading complex of DNA CC polymerase III plus single-stranded binding protein (SSB) CC (PubMed:10801133). RecA and to a lesser extent the beta clamp- CC complex may target Pol V to replication complexes stalled at DNA CC template lesions (PubMed:10801133). {ECO:0000269|PubMed:10801133}. CC -!- INTERACTION: CC Self; NbExp=6; IntAct=EBI-1122622, EBI-1122622; CC P04152:umuC; NbExp=4; IntAct=EBI-1122622, EBI-1119849; CC -!- INDUCTION: Repressed by LexA, induced by DNA damage CC (PubMed:10760155). Induced 1.5-fold by hydroxyurea CC (PubMed:20005847). {ECO:0000269|PubMed:10760155, CC ECO:0000269|PubMed:20005847}. CC -!- SIMILARITY: Belongs to the peptidase S24 family. {ECO:0000305}.
