Protein Structure
UniProt Annotation
Function Defensin 1 and defensin 2 have antibacterial, fungicide and antiviral activities. Has antimicrobial activity against Gram- negative and Gram-positive bacteria. Defensins are thought to kill microbes by permeabilizing their plasma membrane. {ECO:0000269PubMed:15616305, ECO:0000269PubMed:17452329}.
