Signal transduction and cell fate specification during Caenorhabditis elegans vulval development.
A receptor tyrosine kinase/Ras signaling pathway controls the specification of vulval cell fates in Caenorhabditis elegans. Recently, C. elegans genes encoding proteins with similarity to mammalian Raf (lin-45), mitogen-activated protein kinase (mpk-1/sur-1), and an HNF-3 transcription factor (lin-31) have been identified and shown to act downstream of let-60 (ras) in this pathway. These genetically identified gene products bridge the gap between signal transduction at the plasma membrane and the control of cell fate specification in the nucleus.
