  • 蛋白标签：
    N-terminal 10xHis-tagged
  • 产品提供形式：
    Liquid or Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 缓冲液：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

  • 功能：
    Gustatory and odorant receptor which mediates acceptance or avoidance behavior, depending on its substrates. Gr21a and Gr63a together are sufficient for carbon dioxide detection and avoidance behavior. It is possible that the CO(2) receptors Gr63a and Gr21a activate the TRPC channels through Galpha49B and Plc21C. This innate olfactory avoidance behavior can be inhibited by inhibitory interactions of the odors such as 1-hexanol and 2,3-butanedione with Gr21a and Gr63a.
