Supplementary information

USP1 also known as ubiquitin-specific peptidase 1 is a deubiquitinating enzyme with a molecular mass of approximately 88 kDa. It removes ubiquitin from protein substrates especially those involved in DNA repair processes. USP1 is widely expressed in human tissues with high expression in the testis and moderate levels in the lungs brain and heart. It forms a complex with UAF1 which enhances its catalytic activity and stability.
Biological function summary

USP1 plays a critical part in maintaining genomic stability by regulating key proteins in the DNA damage response. It specifically deubiquitinates FANCD2 and PCNA proteins important for the Fanconi anemia pathway and translesion DNA synthesis respectively. This action prevents the accumulation of ubiquitinated proteins ensuring proper progression of DNA repair processes. The interaction with UAF1 forms a functional complex important for its activity in vivo.

Pathways

USP1 is significant in the Fanconi anemia (FA) and translesion synthesis pathways. Its interaction with FANCD2 involves DNA repair by promoting error-free replication across DNA lesions. USP1 also acts on proliferating cell nuclear antigen (PCNA) a protein important for translesion synthesis that enables DNA replication to occur past unrepaired lesions. These pathways highlight USP1’s importance in DNA repair and replication linking it to other proteins like RAD18 which is involved in PCNA ubiquitination.

Research implicates USP1 in cancer and Fanconi anemia. In certain cancers altered USP1 expression can lead to increased DNA repair activity contributing to chemoresistance. USP1’s interaction with FANCD2 makes it pertinent to Fanconi anemia where its malfunction can cause DNA repair defects associated with the disease. Understanding USP1’s role alongside proteins like BRCA1 which interacts with DNA damage repair mechanisms can guide targeted therapeutic strategies.

General info

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, PubMed : 20147293). Has almost no deubiquitinating activity by itself and requires the interaction with WDR48 to have a high activity (PubMed : 18082604, PubMed : 26388029).

Sequence similarities

Belongs to the peptidase C19 family.

Post-translational modifications

Autocatalytic cleavage of USP1 following UV irradiation inactivates it, leading to an increase in ubiquitinated PCNA, recruitment of POLH and translesion synthesis.. Ubiquitin carboxyl-terminal hydrolase 1, N-terminal fragment. Ubiquitinated by the CRL2(KLHDC2) complex following autocatalytic cleavage, leading to its degradation: the CRL2(KLHDC2) complex recognizes the diglycine (Gly-Gly) at the C-terminus.
