Human Odorant Binding Protein 2A

Human Odorant Binding Protein 2A is a 155 amino acid (excluding the signal peptide) lipocalin of relatively low molecular weight (19318 Daltons). Structurally it forms an 8 sheet beta barrel flanked by a c-terminal alpha helix that together forms an internal hydrophobic pore known as a calix. It is secreted by the olfactory epithelial cells of the nose where it lies in high abundance within nasal mucus. Its primary function in the human body is believed to be in the transport of hydrophobic odorant proteins across the otherwise impenetrable aqueous mucus layer to the olfactory receptors of the nose. Due to its high specificity and abundance within nasal mucus, OBP2A was selected as the protein for use in nasal mucus detection.
