UniProtKB description:  Potent broad-spectrum antibacterial peptide against both Gram-positive (B.subtilis, S.epidermidis, and S.aureus) and Gram-negative bacteria (E.coli, S.typhimurium, and P.aeruginosa) (PubMed:20721297, PubMed:23137439). Is also active against all antibiotic-resistant bacterial strains tested (PubMed:23137439). Induces apoptosis in C.albicans, but does not disrupt the fungal plasma membrane at all (PubMed:22542795). Acts by permeabilizing the bacterial cell membrane, but not human membranes (PubMed:23137439). Also shows potent anti-inflammatory activities, since it reduces both LPS-induced nitric oxide release and pro-inflammatory cytokine production (PubMed:23137439). Anti-inflammatory activities are initiated by suppressing the binding of LPS to toll-like receptor 4 (TLR4), and subsequently inhibiting the phosphorylation of p38 mitogen-activated protein kinase (MAPK) and nuclear translocation of NF-kB (TNFRSF11A) (PubMed:23137439). Does not show hemolytic activity against human erythrocytes (PubMed:23137439).
