Abstract
In this issue of Cell, Inoue et al. (2004) reports that LIN-18, an atypical receptor tyrosine kinase related to mammalian Ryk and Drosophila Derailed, mediates Wnt signaling in parallel to LIN-17/Frizzled (Fz) during worm vulval development. LIN-18/Ryk and LIN-17/Fz appear to exhibit distinct Wnt specificity, and surprisingly, the LIN-18 intracellular domain may be dispensable.
