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

This gene encodes 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. [provided by RefSeq, Jul 2008].

Function: DCD-1 displays antimicrobial activity thereby limiting skin infection by potential pathogens in the first few hours after bacterial colonization. Highly effective against E.coli, E.faecalis, S.aureus and C.albicans. Optimal pH and salt concentration resemble the conditions in sweat .

Function: Survival-promoting peptide promotes survival of neurons and displays phosphatase activity. It may bind IgG.
