Anti-Wntless/Gpr177 Antibody

This rabbit polyclonal antibody was generated against a synthetic peptide and and is reactive for the sequence CDGPTEIYKLTRKEAQE of human, mouse and rat G protein-coupled receptor 177 (Wntless/Gpr177).


  • Reacts with human, mouse and rat Wntless/Gpr177
  • Suitable for Western Blot, Immunofluorescence and Immunohistochemistry applications

G protein-coupled receptor 177 (Gpr177), is the mammalian homologue of Drosophila Wntless (Wls; aka Evi, Srt) is required for Wnt secretion in Wnt-producing cells [1-3]. Wntless binds to lipid modified Wnts, and is mainly localized in the Golgi and trafficking vesicles to modulates intracellular sorting of Wnt proteins [1]. It has been demonstrated that genetic inactivation of Wntless in mice causes similar defects to the loss of canonical Wnt [4-10] as well as non-canonical Wnt signaling [16]. However, the loss of Wntless does not affect Wnt expression but Wnt secretion in the signal-producing cells [1, 6]. Wntless is also associated with the retromer complex to recycle Wnt from the plasma membrane [11-15]. The expression pattern of Wntless provides critical information for Wnt-producing cells and source of Wnt in development and disease.
