Zinc finger and BTB domain-containing protein 1 (ZBTB1)

Acts as a transcriptional repressor (PubMed:20797634). Represses cAMP-responsive element (CRE)-mediated transcriptional activation (PubMed:21706167).

Additionally, has a role in translesion DNA synthesis. Requires for UV-inducible RAD18 loading, PCNA monoubiquitination, POLH recruiting to replication factories and efficient translesion DNA synthesis (PubMed:24657165).
