CC   -!- FUNCTION: May have the capacity to recognize and bind specific classes
CC       of odorants. May act as a carrier molecule, transporting odorants
CC       across the mucus layer to access receptor sites. May serve as a primary
CC       defense mechanism by recognizing and removing potentially harmful
CC       odorants or pathogenic microorganisms from the mucosa or clearing
CC       excess odorant from mucus to enable new odorant stimuli to be received.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Highly expressed in olfactory mucosa but
CC       undetectable in thymus, kidney, lung, brain, spleen and liver.
CC   -!- SIMILARITY: Belongs to the BPI/LBP/Plunc superfamily. BPI/LBP family.
CC       {ECO:0000305}.
