Overview
USP1 Negative regulator of DNA damage repair which specifically deubiquitinates monoubiquitinated FANCD2. Also involved in PCNA-mediated translesion synthesis (TLS) by deubiquitinating monoubiquitinated PCNA. Has almost no deubiquitinating activity by itself and requires the interaction with WDR48 to have a high activity. Interacts with FANCD2 and PCNA. Interacts with WDR48. Down-regulated following DNA damage. Belongs to the peptidase C19 family. Note: This description may include information from UniProtKB.
Protein type: Ubiquitin-specific protease; EC 3.4.19.12; EC 3.1.2.15; Ubiquitin conjugating system; Protease
Cellular Component: nucleoplasm; nucleus
Molecular Function: ubiquitin thiolesterase activity; protein binding; cysteine-type endopeptidase activity; ubiquitin-specific protease activity
Biological Process: ubiquitin-dependent protein catabolic process; regulation of DNA repair; protein deubiquitination; DNA repair; response to UV
Reference #:  O94782 (UniProtKB)
