RA   Vassilevski A., Grishin E.;
RL   Submitted (SEP-2018) to UniProtKB.
CC   -!- FUNCTION: Disrupts cell membranes, particularly those rich in
CC       phosphocholine, through formation of pores. Has antimicrobial activity,
CC       hemolytic activity and insecticidal activity.
CC       {ECO:0000250|UniProtKB:P83247}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|Ref.1}. Target cell
CC       membrane {ECO:0000250|UniProtKB:P83247}. Note=Forms a transmembrane
CC       alpha-helix in the target cell membrane. Forms a membrane channel in
CC       the prey. {ECO:0000250|UniProtKB:P83247}.
CC   -!- MASS SPECTROMETRY: Mass=5233.1; Mass_error=0.5; Method=MALDI;
CC       Evidence={ECO:0000269|Ref.1};
CC   -!- SIMILARITY: Belongs to the cationic peptide 02 (oxyopinin-2) family.
CC       {ECO:0000305}.
