RT   antibacterial peptides from the common cutworm, Spodoptera litura.";
RL   Comp. Biochem. Physiol. 125C:287-297(2000).
CC   -!- FUNCTION: Cecropins have lytic and antibacterial activity against
CC       several Gram-positive and Gram-negative bacteria.
CC       {ECO:0000269|PubMed:11790350}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:11790350}.
CC   -!- INDUCTION: Induced as part of the humoral response to a bacterial
CC       invasion. Transcripts appear within the immunized fat body.
CC       {ECO:0000269|PubMed:11790350}.
CC   -!- SIMILARITY: Belongs to the cecropin family. {ECO:0000305}.
