The mec-3 gene of Caenorhabditis elegans requires its own product for maintained expression and is expressed in three neuronal cell types.


The homeo-box-containing gene mec-3 of the nematode Caenorhabditis elegans, is expressed in several sensory neurons, as assayed by expression of a mec-3-lacZ fusion. These cells are the touch receptors, which mediate the response to gentle touch, and the FLP and PVD neurons. PVD mediates a response to harsh mechanical stimuli, and FLP has an ultrastructure… (More)
