CC   -!- FUNCTION: Has antibacterial, fungicide and antiviral activities. Has
CC       antimicrobial activity against Gram-negative and Gram-positive
CC       bacteria. Defensins are thought to kill microbes by permeabilizing
CC       their plasma membrane (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Dimer. Interacts with RETN. {ECO:0000250|UniProtKB:P59665}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- PTM: ADP-ribosylation drastically reduces cytotoxic and antibacterial
CC       activities, and enhances IL8 production. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the alpha-defensin family. {ECO:0000305}.
