CC   -!- FUNCTION: Host defense peptide that exhibits antimicrobial activity
CC       against both Gram-negative bacteria, such as E.coli and S.typhimurium,
CC       and Gram-positive bacteria, such as S.aureus and B.subtilis (By
CC       similarity). Inhibits cell adhesion of E.coli on intestinal epithelial
CC       enterocytes (By similarity). Causes rapid permeabilization of both the
CC       outer and inner membrane of E.coli, leading to morphological
CC       alterations on the bacterial surface (By similarity). Binds to
CC       bacterial lipopolysaccharides (LPS) with high affinity, and may thereby
CC       be involved in immunoregulation through LPS neutralization (By
CC       similarity). May contribute to epididymal innate immunity and protect
CC       the sperm against attack by microorganisms (By similarity).
CC       {ECO:0000250|UniProtKB:Q96PH6}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q96PH6}.
CC   -!- PTM: The three-dimensional structure formed by the three intramolecular
CC       disulfide bridges is indispensable for antimicrobial activity.
CC       {ECO:0000250|UniProtKB:Q96PH6}.
CC   -!- SIMILARITY: Belongs to the beta-defensin family. {ECO:0000305}.
