Beta-defensin 129 is a protein that in humans is encoded by the DEFB129 gene.Defensins are cysteine-rich cationic polypeptides that are important in the immunologic response to invading microorganisms. The protein encoded by this gene is secreted and is a member of the beta defensin protein family. Beta defensin genes are found in several clusters throughout the genome with this gene mapping to a cluster at 20p13.
