Scientific Data

Western Blot Detection of Human/Mouse/Rat IMP2 antibody by Western Blot. View Larger

Detection of Human/Mouse/Rat IMP2 by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, A431 human epithelial carcinoma cell line, Caco-2 human colorectal adenocarcinoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, and Y3-Ag rat myeloid cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat IMP2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5305) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). Specific bands were detected for IMP2 at approximately 62 to 68 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 1.

Background: IMP2

IMP2 (IGF-II mRNA-binding protein 2; also VICKZ family member 2) is a 62 kDa member of the RRM IMP/VICKZ family of proteins. It is expressed in oocytes, spermatogonia, Leydig cells and follicular granulosa cells. IMP2 binds to AUF1, a binding protein for the AU-rich motifs of mRNA, and facilitates the degradation of cytokine and protooncogene mRNAs. Human IMP2 is 556 amino acids (aa) in length. It contains two RNA recognition regions (aa 3‑76 and 82‑157), and four KH domains (aa 193‑532) that mediate RNA binding. There are multiple splice variants. One shows an insertion of 43 aa after Asn357, a second shows a 17 aa substitution for the N-terminal 80 aa, a third shows a combination of the prior two, and a fourth shows a 15 aa substitution for aa 414‑556. Over aa 1‑220, human IMP2 is 89% aa identical to mouse IMP2.
