Anti-USP33 antibodies are used in the immunodetection of the protein ubiquitin specific peptidase 33. In humans, the canonical protein has a reported length of 942 amino acid residues and a mass of 106.7 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Peptidase C19 protein family, USP33 is known to be a deubiquitinating enzyme involved in various processes such as centrosome duplication, cellular migration and beta-2 adrenergic receptor/ADRB2 recycling. Synonyms for this target antigen include ubiquitin carboxyl-terminal hydrolase 33, VHL-interacting deubiquitinating enzyme 1, deubiquitinating enzyme 33, pVHL-interacting deubiquitinating enzyme 1, and VDU1. USP33 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of USP33 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
