CC   -!- FUNCTION: Peptide which can recruit, activate and subsequently lyse
CC       human neutrophils, thus eliminating the main cellular defense against
CC       infection. Stimulates the secretion of the chemotactic factor
CC       interleukin-8 (IL-8). The ensuing activation process triggers an
CC       inflammatory response in the host, thus contributing greatly to
CC       virulence. Also possesses hemolytic activity, which may contribute to
CC       the development of disease. {ECO:0000269|PubMed:17994102}.
CC   -!- INDUCTION: Up-regulated by agr. {ECO:0000269|PubMed:17994102}.
CC   -!- MISCELLANEOUS: Peptide production is higher in most prevalent
CC       community-associated MRSA strains than in hospital-associated MRSA
CC       strains.
CC   -!- SIMILARITY: Belongs to the phenol-soluble modulin alpha peptides
CC       family. {ECO:0000305}.
