Abstract
The Wnt family of signaling proteins mediates cell-cell communication during development. In this issue of Cell, Bänziger et al. (2006) and Bartscherer et al. (2006) identify Wntless/Evi, a multipass transmembrane protein in the secretory pathway of Wnt-producing cells that promotes Wnt secretion.
