Scientific Data

Western Blot Detection of Human WTX antibody by Western Blot. View Larger

Detection of Human WTX by Western Blot. Western blot shows lysates of U937 human histiocytic lymphoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human WTX Monoclonal Antibody (Catalog # MAB7374) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for WTX at approximately 190 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

WTX in BG01V Human Embryonic Stem Cells. WTX was detected in immersion fixed BG01V human embryonic stem cells using Mouse Anti-Human WTX Monoclonal Antibody (Catalog # MAB7374) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: WTX

WTX (Wilms Tumor on the X; also FAM123B and AMER1) is a 190-200 kDa member of the FAM123 family of proteins. It is widely expressed in both adult and embryo and appears to have at least three functions: one, it binds WT1 in the nucleus and regulates cell differentiation; two, it associates with the plasma membrane and draws APC away from microtubules, thereby participating in intercellular junction integrity; and three, it binds beta -catenin and impacts WNT signaling. Human WTX is 1135 amino acids in length. It contains a PtdIns-P2 binding site (aa 2-209), an acidic domain (aa 370-411), and a Pro-rich region (aa 952-1104). There are three APC binding motifs (aa 280-368; 380-431; 717-834) and the beta -catenin binding region lies C-terminal to Gly368. There are two isoform variants. One is 150 kDa in size, nuclear in location, and shows a deletion of aa 50-326. A second shows a 19 aa substitution for aa 786-1135. Over aa 421-573, human WTX shares 89% aa identity with mouse WTX.
