Components 1 kit Human USP1 knockout HeLa cell lysate (Lyophilized) 1 x 100µg Human Wild Type HeLa cell lysate (Lyophilized) 1 x 100µg
FunctionNegative 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.
Sequence similaritiesBelongs to the peptidase C19 family.
Developmental stageCell cycle-regulated. Highest level during S phase.
modificationsAutocatalytic cleavage of USP1 following UV irradiation inactivates it leading to an increase in ubiquitinated PCNA, recruitment of POLH and translesion synthesis.
Ubiquitinated; leading to its subsequent proteasomal degradation.
Phosphorylated upon DNA damage, probably by ATM or ATR.
