CC   -!- FUNCTION: Linear cationic alpha-helical peptide that acts as
CC       antimicrobial peptide by forming pore in membrane. Has antibacterial
CC       activities against both Gram-positive and Gram-negative strains. Has
CC       more potent activities against the yeast C.albicans. Shows moderate
CC       mast cell degranulation and leishmanicidal activities. Has a very low
CC       hemolytic activity. {ECO:0000269|PubMed:21549739}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:21549739}. Target
CC       cell membrane {ECO:0000269|PubMed:21549739}. Note=Assumes an
CC       amphipathic alpha-helical conformation in a lipid environment. Forms a
CC       membrane channel in the prey (By similarity). {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom g.
CC       {ECO:0000305|PubMed:21549739}.
CC   -!- MASS SPECTROMETRY: Mass=1474.9; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:21549739};
CC   -!- SIMILARITY: Belongs to the MCD family. Mastoparan subfamily.
CC       {ECO:0000305}.
