Anti-USP7 antibodies are used in the immunodetection of the protein ubiquitin specific peptidase 7. In humans, the canonical protein has a reported length of 1102 amino acid residues and a mass of 128.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in neural progenitor cells. A member of the Peptidase C19 protein family, USP7 is a reported hydrolase that deubiquitinates target proteins such as FOXO4, KAT5, p53/TP53, MDM2, ERCC6, DNMT1, UHRF1, PTEN, KMT2E/MLL5 and DAXX. Synonyms for this target antigen include DEL16P13.2, HAFOUS, HAUSP, TEF1, ubiquitin carboxyl-terminal hydrolase 7, and C16DELp13.2. USP7 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 230 citations in the literature describe the use of USP7 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
