Scientific Data

Western Blot Detection of Human ISG15/UCRP antibody by Western Blot. View Larger

Detection of Human ISG15/UCRP by Western Blot. Western blot shows lysates of DLD-1 clone 2C2 human colon adenocarcinoma cell line, HT-29 human colon adenocarcinoma cell line, and CCD-1070Sk human foreskin fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Human ISG15/UCRP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4845) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for ISG15/UCRP at approximately 15 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Background: ISG15/UCRP

ISG15 (interferon-induced 15 kDa protein; also IP17) is a 15 kDa ubiquitin family protein that is expressed by a wide variety of cell types. ISG15 is induced by type I IFN, and like ubiquitin, becomes conjugated to intracellular proteins. Unlike ubiquitin, it does not target proteins for degradation, instead, it is part of the anti‑virus response. Human proISG15 is 165 amino acids (aa) in length. There are two ubiquitin-like domains (aa 2‑78 and 79‑157) and a propeptide (aa 15‑165) that is cleaved intracellularly. Select blood mononuclear cells secrete mature ISG15, which is chemotactic for neutrophils. Mature human ISG15 is 66% aa identical to mouse ISG15.
