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.
