PhysiologyIn Caenorhabditis elegans, the asp-1 gene is exclusively transcribed in the intestinal cells, with the highest levels of expression observed at late embryonic and early larval stages of development. Transcription is not observed in the adult nematodes or mature larvae (Tcherepanova et al., 2000).
