long palate, lung & nasal epithelium carcinoma-associated protein 3; BPI fold-containing family B member 3; ligand-binding protein RYA3 (BPIFB3, C20orf185, LPLUNC3)

Function

• recognition & binding of specific classes of odorants
• carrier protein, transporting odorants across the mucus layer to access receptor sites (putative)
• primary defense mechanism: (putative) recognition & removal from the mucosa of
  • potentially harmful odorants
  • pathogenic microorganisms
• clearing excess odorant from mucus to enable new odorant stimuli to be received

Structure

• belongs to the BPI/LBP/plunc superfamily, BPI/LBP family

Compartment

secreted

Expression

expressed in nasal septal epithelium

More general terms
