- Extra Details:
- Defensins are small cysteine-rich cationic proteins found in both vertebrates and invertebrates. They have also been reported in plants. They are active against bacteria, fungi and many enveloped and nonenveloped viruses. They consist of aa18-45 including six (in vertebrates) to 8 conserved cysteine residues. Cells of the immune system contain these peptides to assist in killing phagocytized bacteria, for example in neutrophil granulocytes and almost all epithelial cells. Most defensins function by binding to microbial cell membrane, and once embedded, forming pore-like membrane defects that allow efflux of essential ions and nutrients. alpha-defensins expressed primarily in neutrophils as well as in NK cells and certain T-lymphocyte subsets. DEFA5 and DEFA6 are expressed in Paneth cells of the small intestine, where they may regulate and maintain microbial balance in the intestinal lumen.
