• Background：
• function:Exhibits antimicrobial activity against Gram-positive bacteria S.aureus and S.pyogenes, Gram-negative bacteria P.aeruginosa and E.coli and the yeast C.albicans. Kills multiresistant S.aureus and vancomycin-resistent E.faecium. No significant hemolytic activity was observed.,induction:By infection of bacteria and by interferon gamma.,mass spectrometry: PubMed:11085990,similarity:Belongs to the beta-defensin family.,tissue specificity:Highly expressed in skin and tonsils, and to a lesser extent in trachea, uterus, kidney, thymus, adenoid, pharynx and tongue. Low expression in salivary gland, bone marrow, colon, stomach, polyp and larynx. No expression in small intestine.,
