Dermcidin is a protein that in humans is encoded by the DCD gene.^[2][3] Dermcidin is an anti-microbial (antibiotic) peptide released by human sweat glands.

Function

Dermcidin is a secreted protein that is subsequently processed into mature peptides of distinct biological activities. The C-terminal peptide is constitutively expressed in sweat and has antibacterial and antifungal activities. The N-terminal peptide, also known as diffusible survival evasion peptide, promotes neural cell survival under conditions of severe oxidative stress. A glycosylated form of the N-terminal peptide may be associated with cachexia (muscle wasting) in cancer patients.^[3]
