Abstract:
The recent completion of the Caenorhabditis elegans genome has revealed that this nematode worm has 10 members of the ETS gene family. Isolation and analysis of C. elegans mutants and subsequent screens to identify interacting genes can proceed very quickly in this model organism. Molecular genetic analysis of the receptor tyrosine kinase-Ras-MAP kinase signaling pathway in C. elegans identified the ETS family transcription factor Lin-1 as a nuclear effector of this evolutionarily conserved signal transduction pathway. Here we review classical genetic approaches used to discover the role of Lin-1 in the Ras-MAP kinase signaling pathway and describe new technologies that can be applied to the analyses of signaling pathways and transcription factor regulatory networks in C. elegans.
