[Hugh M Robertson].I've recognized five C. elegans genes as members of a large family of gustatory receptors (about 60 total) in the Drosophila genome originally described by John Carlson's laboratory. Phylogenetically they form three distinct lineages within this family, indicating that the family predates the nematode/arthropod split. In the absence of functional, mutant, or expression data, I prefer to name them in the least definitive manner possibl, but indicating that they are candidate receptors (seven-TM superfamily) related to the gustatory receptors of Drosophila.
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
