title: From sensing cellular sterols to assembling sensory structures.
abstract: The genome of the nematode C. elegans is peppered with novel genes belonging to a superfamily whose members function in cellular cholesterol homeostasis (Niemann-Pick C1) and Hedgehog signal transduction (Patched) and biogenesis (Dispatched). In this issue of Developmental Cell and an analysis of a pair of Patched- and Dispatched-related proteins in C. elegans extends the superfamily's repertoire to include the formation of tubular organs.
