Anti-USP44 antibodies are used in the immunodetection of the protein ubiquitin specific peptidase 44. In humans, the canonical protein has a reported length of 712 amino acid residues and a mass of 81.2 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably expressed in the testis. A member of the Peptidase C19 protein family, USP44 is a reported deubiquitinase that plays a key regulatory role in the spindle assembly checkpoint or mitotic checkpoint by preventing premature anaphase onset. Post-translational modifications have been described, including ubiquitination and phosphorylation. Synonyms for this target antigen include deubiquitinating enzyme 44, ubiquitin specific protease 44, ubiquitin thioesterase 44, ubiquitin thiolesterase 44, ubiquitin-specific-processing protease 44, and ubiquitin carboxyl-terminal hydrolase 44. USP44 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of USP44 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
