Defensins (DEF) are small cationic defense proteins active against bacteria, fungi and viruses. DEF contains 6-8 conserved cysteine residues. DEF binds to microbial cell membrane forming pores and thus allowing outflow of essential nutrients. There is increase in α-DEF in chronic inflammations and several cancers. For details on plant DEF see Plant defensing.
