CC   -!- FUNCTION: Has bactericidal activity. May act as a ligand for C-C
CC       chemokine receptor CCR6. Positively regulates the sperm motility and
CC       bactericidal activity in a CCR6-dependent manner. Binds to CCR6 and
CC       triggers Ca2+ mobilization in the sperm which is important for its
CC       motility. {ECO:0000250|UniProtKB:P60022}.
CC   -!- SUBUNIT: Monomer. Homodimer. {ECO:0000250|UniProtKB:P60022}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P60022}. Membrane
CC       {ECO:0000250|UniProtKB:P60022}. Note=Associates with tumor cell
CC       membrane-derived microvesicles. {ECO:0000250|UniProtKB:P60022}.
CC   -!- SIMILARITY: Belongs to the beta-defensin family. {ECO:0000305}.
