Comments Information

    • Function

    • Has antibacterial activity against several Gram-positive and Gram-negative bacteria. Is weakly active against yeasts. Acts by a nonpore mechanism.

    • Tissue specificity

    • Expressed in the body wall, intestine, uterus and ovary.

    • Induction

    • Induced as part of the humoral response to a bacterial invasion. Transcripts appear within the immunized fat body.
