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 family is composed of pheromone binding proteins (PBP) and general odorant binding proteins (GOBP) from insects.
Aed a 2 is a salivary allergen from the yellow-fever mosquito Aedes aegypti . Homologous allergens were also identified in other mosquito species.
Family-defining Pfam domains (at least one of these domains is present in each family member):
