R-Spondin Proteins: A Novel Link to β-catenin Activation
5 Dec 2005
Abstract excerpt
The R-spondin (Rspo) protein family is a recently described group of four distinct human secreted proteins. Reported activities for Rspo proteins include essential roles in vertebrate development and their ligand-type activities overlap substantially with those of the canonical Wnt ligands in that both Rspo and canonical Wnt signaling result in the activation of beta-catenin. In a general functional screen for...
