Serpentine receptor class alpha-39 [Caenorhabditis elegans]

Protein Classification

serpentine receptor Sra family protein( domain architecture ID 27938)

serpentine receptor Sra family protein such as Sra, Srab, Srb, and Sre; they belong to a family of seven-transmembrane (7TM) G protein-coupled receptors involved in chemoreception, a central sense of soil nematodes like Caenorhabditis elegans

18-326 9.11e-09

Serpentine type 7TM GPCR receptor class ab chemoreceptor; 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. Srab is part of the Sra superfamily of chemoreceptors. Chemoperception is one of the central senses of soil nematodes like C. elegans which are otherwise 'blind' and 'deaf'. The expression pattern of the srab genes is biologically intriguing. Of the six promoters successfully expressed in transgenic organizms, one was exclusively expressed in the tail phasmid neurons, two were exclusively expressed in a head amphid neuron, and two were expressed both in the head and tail neurons as well as a limited number of other cells.

116-253 2.36e-03

C. elegans Sre G protein-coupled chemoreceptor; Caenorhabditis elegans Sre proteins are candidate chemosensory receptors. There are four main recognized groups of such receptors: Odr-10, Sra, Sro, and Srg. Sre (this family), Sra pfam02117 and Srb pfam02175 comprise the Sra group. All of the above receptors are thought to be G protein-coupled seven transmembrane domain proteins. The existence of several different chemosensory receptors underlies the fact that in spite of having only 20-30 chemosensory neurones, C. elegans detects hundreds of different chemicals, with the ability to discern individual chemicals among combinations.
