Protein

BPI fold-containing family B member 3

Gene

BPIFB3

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

May have the capacity to recognize and bind specific classes of odorants. May act as a carrier molecule, transporting odorants across the mucus layer to access receptor sites. May serve as a primary defense mechanism by recognizing and removing potentially harmful odorants or pathogenic microorganisms from the mucosa or clearing excess odorant from mucus to enable new odorant stimuli to be received (By similarity).By similarity
