Chemoreception is mediated in Caenorhabditis elegans by membersof the seven-transmembrane G-protein-coupled receptor class (7TM GPCRs) of proteins which are of the serpentine type [1]. Srw is a solo family amongst the superfamilies of chemoreceptors. Chemoperception is one of the central senses of soil nematodes like C. elegans which are otherwise 'blind' and 'deaf' [2]. The genes encoding Srw do not appear to be under as strong an adaptive evolutionary pressure as those of Srz [3].
