Molecular Profile

What Is LL-37?

A 37-residue cationic, amphipathic alpha-helical peptide released by proteolytic cleavage from the C-terminus of the 18-kDa human cathelicidin protein hCAP-18. It is the only cathelicidin-derived antimicrobial peptide found in humans and is expressed by neutrophils and epithelial cells. The name comes from its two N-terminal leucines and its length (37 residues).
