This N-terminal HA-tagged ISG15 is a potent, irreversible and specific inhibitor of ISG15-specific isopeptidases (such as UBP43, Cat # E-600). This protein blocks the hydrolysis of poly-ISG15 chains on substrate proteins in vitro and thus enhances poly-ISG15 chain accumulation. The HA peptide sequence (YPYDVPDYA) is derived from the influenza hemagglutinin protein. This epitope allows for the sensitive identification or purification of such deconjugating activities since it is specifically recognized by anti-HA antibodies and/or anti-HA-agarose.
