NCBI Summary for DEFB103A

Defensins form a family of microbicidal and cytotoxic peptides made by neutrophils. Members of the defensin family are highly similar in protein sequence. This gene encodes defensin, beta 103, an antibiotic peptide which is induced by bacteria and interferon gamma, and which displays antimicrobial activity against S. aureus, S. pyogenes, P. aeruginosa, E. coli, and C. albicans.
