7TM_GPCR_Srsx

7TM_GPCR_Srsx
PFAM accession number:PF10320
Interpro abstract (IPR019424):

Chemoreception is mediated in Caenorhabditis elegans by members of the seven-transmembrane G-protein-coupled receptor class (7TM GPCRs) of proteins which are of the serpentine type [ (PUBMED:7585938) ]. Srsx 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' [ (PUBMED:18050473) ].
