Detection of Human and Mouse Pygopus‑1 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and NIH-3T3 mouse embryonic fibroblast cell line. Gels were loaded with 30 µg of whole cell lysate (WCL), 20 µg of cytoplasmic (Cyto), and 10 µg of nuclear extracts (Nuc). PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human/Mouse Pygopus-1 Mono-clonal Antibody (Catalog # MAB3617) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Pygopus-1 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Background: Pygopus-1

Human Pygopus-1 (PYGO1, the name of a legless Australian lizard) is a 45 kDa, 419 amino acid (aa) transcriptional coactivator. It contains four domains: an N‑terminal NLS (aa 35‑41), followed by a Pro-rich, Asn-rich, and zinc-finger PHD-type domain (aa 340‑398). It is a nuclear protein that acts in concert with BCL-9 to retain beta -catenin in the nucleus during Wnt-signaling. In particular, following beta -catenin activation and translocation to the nucleus, beta -catenin first binds to BCL-9 in a phosphorylation-independent manner. Its continued presence in the nucleus depends upon BCL-9 binding to Pygopus. Once anchored, beta -catenin interacts with TCF to activate Wnt-responsive genes. Human Pygopus-1 shares 87% aa sequence identity with mouse Pygopus-1.
