Protein function: 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). [The UniProt Consortium]
synthetic peptide. The epitope recognized by A301-700A-T maps to a region between residue 584 and 634 of human ubiquitin-specific-processing protease 1 using the numbering given in entry NP_003359.3 (GeneID 7398).
