This family consists of a group of Drosophila melanogaster proteins of unknown function. A number of these proteins are expressed in nonneuronal auxiliary cells within two nested subsets of chemosensory sensilla on the front legs of male D. melanogaster, suggesting they may be involved in pheromone response [ PUBMED:11904775 ]. These proteins are predicted to have a single transmembrane domain at their amino terminus, probably to serve as a signal peptide, suggesting that they are soluble and secreted.
