Anti-ISG15/UCRP Antibody

32160702

ISG15 (also called ubiquitin cross-reactive protein (UCRP) due to its cross-reactivity with ubiquitin antibodies) was originally identified as an interferon stimulated gene (ISG) whose expression is highly induced upon interferon treatment. ISG15 contains two ubiquitin homology domains in tandem and shows ~30% identity to ubiquitin. Unlike ubiquitin, that is almost 100% homologous across species, ISG15 is only conserved in dispersed regions. Homology among the five identified mammalian ISG15 proteins is only about 47%. Like other Ubls, ISG15 is synthesized as a 17-kDa precursor form and processed to 15- kDa protein by a specific protease in order to expose di-glycine residues at the carboxyl terminal which is critical for subsequent conjugation to target proteins.

Antibody 09-412 recognizes several members of the ubiquitin-like (Ubl) family including ubiquitin, SUMO-1, SUMO-2, SUMO-3, Nedd8, FAT10, Ubl5, Urm1 and Fub1. This antibody shows no cross-reactivity with any of these Ubls in recombinant form upon Western blotting under the conditions used.

Peptide corresponding to residues 85-101 of human ISG15.
