title: Expression of Xenopus homologs of the beta-catenin binding protein pontin52.
abstract: Identification of pontin52 as an interaction partner of the Wnt/Wg signal transducer beta-catenin implicated a role for this protein in Wnt signaling. Here we describe the isolation of two Xenopus homologs of pontin52, Xpontin and Xreptin, and report the first expression pattern of vertebrate pontin52 homologs. Whole-mount in situ hybridization studies reveal a strong expression of Xpontin in neural crest cells and in later stages in different gastrointestinal organs. Xreptin is also expressed in neural crest cells, in particular in a subpopulation that give raise to the adrenal medulla.
