CC -!- FUNCTION: Antimicrobial peptide with activity against Gram-positive and
CC Gram-negative bacteria and against fungi (PubMed:17000029). Has been
CC tested against S.aureus (MIC=5.5 ug/mL), E.coli (MIC=6.5 ug/mL),
CC B.dysenteriae (MIC=2.2 ug/mL), and C.albicans (MIC=7.5 ug/mL)
CC (PubMed:17000029). Can regulate or mediate antimicrobial response by
CC stimulating mast cell degranulation (PubMed:17000029). Induces
CC histamine release (PubMed:17000029). Shows cytotoxicity toward solid
CC tumor cell line HepG2 (PubMed:17000029). Also shows a potent hemolytic
CC activity (LD(50)=5 ug/ml) (PubMed:17000029).
CC {ECO:0000269|PubMed:17000029}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:17000029}.
CC -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC {ECO:0000305|PubMed:17000029}.
CC -!- MASS SPECTROMETRY: Mass=2663.7; Method=FAB;
CC Evidence={ECO:0000269|PubMed:17000029};
CC -!- SIMILARITY: Belongs to the frog skin active peptide (FSAP) family.
CC Brevinin subfamily. {ECO:0000305}.
