Preparation and Storage

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.
