Comments Information

    • 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. Also exhibits proteolytic activity. Survival-promoting peptide promotes survival of neurons and displays phosphatase activity.

    • Catalytic activity

    • Preferential cleavage

    • Cofactor

    • Manganese. Required for survival-promoting peptide.

    • Tissue specificity

    • Specifically and constitutively expressed in eccrine sweat gland cells. Secreted into the sweat at a concentration of 1-10 micrograms/ml.
