Biochemical properties

Odorant-binding proteins are small, water-soluble proteins that solubilize hydrophobic odorant molecules to facilitate their transport to their receptors. The OS-D family is named after a protein identified in the antenna of Drosphila melanogaster. Homologues of OS-D are wide-spread among insects [1]. They share features with vertebrate odorant-binding proteins but show no sequence similarities.

Allergens from this family
