Mas7 Peptide is a mast cell degranulating peptide from the mastoparan family of peptides found in wasp venom. The amphiphilic Mas7 peptide (Mastoparan-L), a structural analogue of mastoparan, is a known activator of heterotrimeric Gi proteins that couple to phospholipase C downstream effectors.Wasp: H-Ile-Asn-Leu-Lys-Ala-Leu-Ala-Ala-Leu-Ala-Lys-Ala-Leu-Leu-NH2 or H-INLKALAALAKALL-NH2
