A small model animal Caenorhabditis elegans is particularly suitable for genetic analysis, but cell-type-specific biochemistry is a formidable task in this organism. Here we describe techniques utilizing transgenic C. elegans strains expressing epitope-tagged proteins for analyzing biochemical events, such as protein phosphorylation and formation of protein complex, in a small number of a specific group of cells at a defined stage of development. The techniques are useful for elucidating that C. elegans semaphorin-plexin signaling systems regulate epidermal morphogenesis through modulating TOR signaling and its downstream targets.
