IMP2/IGF2BP2 Antibody

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 (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.
