DESCRIPTION

Also known as UBP1_HUMAN, USP1. Negative regulator of DNA damage repair which specifically deubiquitinates monoubiquitinated FANCD2 (PubMed:15694335). Also involved in PCNA-mediated translesion synthesis (TLS) by deubiquitinating monoubiquitinated PCNA (PubMed:16531995). Has almost no deubiquitinating activity by itself and requires the interaction with WDR48 to have a high activity (PubMed:18082604, PubMed:26388029). Interacts with FANCD2 and PCNA (PubMed:15694335, PubMed:16531995). Interacts with WDR48 (PubMed:18082604, PubMed:26388029).
