Protein Domain : Pheromone/general odorant binding protein superfamily IPR036728

Type  Homologous_superfamily
Description  The olfactory receptors of terrestrial animals exist in an aqueous environment, yet detect odorants that are primarily hydrophobic. The aqueous solubility of hydrophobic odorants is thought to be greatly enhanced via odorant binding proteins which exist in the extracellular fluid surrounding the odorant receptors [ ]. This superfamily is composed of pheromone binding proteins (PBP), which are male-specific and associate with pheromone-sensitive neurons and general-odorant binding proteins (GOBP).Members of this superfamily has an EF Hand-like fold, which has a core of four helices and an array of two opened hairpins. The N-terminal extension of these domains, containing a few short helices, forms a flexible lid for the binding cavity.
