Anti-ubiquitin specific peptidase 17 like family member 5 antibodies are used for the immunodetection of the protein encoded by the USP17L5 gene. In humans, the canonical protein has a reported length of 530 amino acid residues and a mass of 59.7 kDa. Its subcellular localization is in the nucleus and ER. A member of the Peptidase C19 protein family, it is a type of deubiquitinating enzyme that removes conjugated ubiquitin from specific proteins to regulate different cellular processes that may include cell proliferation, progression through the cell cycle, apoptosis, cell migration, and the cellular response to viral infection. Other names for this target antigen include deubiquitinating enzyme 17-like protein 5, ubiquitin thioesterase 17-like protein 5, ubiquitin thiolesterase 17-like protein 5, and ubiquitin carboxyl-terminal hydrolase 17-like protein 5.
