DCD
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, cleaving on the C-terminal side of Arg and, to a lesser extent, Lys residues. Survival-promoting peptide promotes survival of neurons and displays phosphatase activity. It may bind IgG. Specifically and constitutively expressed in eccrine sweat gland cells. Secreted into the sweat at a concentration of 1-10 micrograms/ml. 3 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
