Abstract: | The Caenorhabditis elegans gene lin-36 acts to antagonize Ras-mediated vulval induction in a pathway that includes genes with products similar to the mammalian retinoblastoma (Rb) protein and the Rb-binding protein p48. We report that lin-36 encodes a novel protein of 962 amino acids. We demonstrate that lin-36 functions in and is expressed in the vulval precursor cells, establishing that the lin-36 pathway is involved in intercellular signaling. We also report that the lin-36 pathway and/or another pathway that is functionally redundant with the lin-36 pathway antagonize a ligand-independent activity of the receptor tyrosine kinase/Ras vulval induction pathway. |
