UBP1 Polyclonal Antibody

catalytic activity:Ubiquitin C-terminal thioester + H(2)O = ubiquitin + a thiol.,developmental stage:Cell cycle-regulated. Highest level during S phase.,function:Negative regulator of DNA damage repair. Autocatalytic cleavage of USP1 leads to an increase in ubiquitinated PCNA, recruitment of POLH and translesion synthesis following DNA damage. Regulates ubiquitination of FANCD2.,miscellaneous:HEK293T cells expressing reduced levels of USP1 show a higher level of ubiquitinated PCNA and an increase in point mutations upon UV irradiation.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,PTM:Ubiquitinated. Degraded by the proteasome.,sequence caution:Contaminating sequence. Potential poly-A sequence.,similarity:Belongs to the peptidase C19 family.,subunit:Interacts with FANCD2.,
