ODORANT BINDING PROTEINS -
Odorant Binding Proteins (OBP) are small (10 to 30 kDa) proteins secreted by auxiliary cells surrounding the olfactory receptor neurons. OBPs are characterized by a specific protein domain that comprises six α-helices joined by three disulfide bonds. Although the full function of the OBPs is not well established, it is believed that they may act as molecular carriers that transport odorants and deliver them to the olfactory receptors located on the sensory neurons. (Adapted from FBrf0205523).
Protein Function (UniProtKB)
Present in the aqueous fluid surrounding olfactory sensory dendrites and are thought to aid in the capture and transport of hydrophobic odorants into and through this fluid.

    Additional comments

    FlyBase curator comment: The gene referred to as "Obp99d" in FBrf0151704 is not the same gene as the one referred to as "Obp99d" in FlyBase (FBgn0039684). The gene referred to as "Obp99d" in FBrf0151704 actually corresponds to FBgn0039685 which is referred to in FlyBase with the symbol "Obp99b" (and corresponds to release 3 annotation CG7592).

    (Hekmat-Scafe et al., 2002)

    FlyBase curator comment: The gene referred to as "Obp99d" in FBrf0151651 is not the same gene as the one referred to as "Obp99d" in FlyBase (FBgn0039684). The gene referred to as "Obp99d" in FBrf0151651 actually corresponds to FBgn0039685 which is referred to in FlyBase with the symbol "Obp99b" (and corresponds to release 3 annotation CG7592).
