CC -!- FUNCTION: Host-defense peptide that has antimicrobial activity against
CC Gram-positive and Gram-negative bacteria and fungi (in vitro)
CC (PubMed:2543629). Exhibits activity against E.coli, A.calcoaceticus,
CC S,aureus and C.albicans (PubMed:2543629). {ECO:0000269|PubMed:2543629}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q01523}.
CC -!- TISSUE SPECIFICITY: Expressed in neutrophils (at protein level)
CC (PubMed:2543629). Highest expression in bone marrow and to a much
CC lesser extent in small intestine (PubMed:7594610).
CC {ECO:0000269|PubMed:2543629, ECO:0000269|PubMed:7594610}.
CC -!- SIMILARITY: Belongs to the alpha-defensin family. {ECO:0000305}.
