RT   "Structural and biological characterization of three novel mastoparan
RT   peptides from the venom of the neotropical social wasp Protopolybia exigua
RT   (Saussure).";
RL   Toxicon 45:101-106(2005).
CC   -!- FUNCTION: Mast cell degranulating peptide. Activates G proteins (Gi
CC       component), which in turn activates the cascade of molecular events
CC       cAMP-regulated, resulting in mast cell degranulation.
CC       {ECO:0000269|PubMed:15581688}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:15581688}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC       {ECO:0000305|PubMed:15581688}.
CC   -!- MASS SPECTROMETRY: Mass=1566.90; Method=Electrospray;
CC       Evidence={ECO:0000269|PubMed:15581688};
CC   -!- SIMILARITY: Belongs to the MCD family. Mastoparan subfamily.
