Scientific Data Images for Human Notum Antibody

Detection of Human Notum antibody by Western Blot.

Detection of Human Notum by Western Blot.

Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Notum Monoclonal Antibody (Catalog # MAB9356) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). Specific bands were detected for Notum at approximately 50-60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Notum

Notum is an evolutionarily conserved 60 kDa secreted deacylase that regulates Wnt activity (1, 2). It is tethered to the cell surface by binding to Glypican-like sulfated proteoglycans, and it functions as a Glypican-dependent Wnt inhibitor (1-4). Notum hydrolyzes the palmitoyl moiety from Wnt-3a, making the Wnt more hydrophilic and unable to bind to the Frizzled-8 receptor (1, 2). It also induces the release of cell surface GPI-anchored proteins such as Glypican-3, Cadherin-13, and uPAR (4). Notum regulates head regeneration in planaria (3), head formation and neural induction in Xenopus (1), and long range activity of hedgehog proteins in Drosophila (5). It is up-regulated in some human hepatocellular carcinomas and colorectal cancers (6, 7). Within amino acids
81-451, human Notum shares 92% aa sequence identity with mouse and rat Notum.
