Recombinant RatDefensin, Beta 1
BD1, DEFB-1, HBD-1

Rat beta-defensin 1 (DEFB1) is an antimicrobial peptide that contributes to the innate and adaptive immune systems and is active against bacteria, fungi, and viruses. Like the other β-defensins, DEFB1 is a small protein that contains a motif consisting of six cysteine residues which form three intramolecular disulfide bridges. It is constitutively expressed in epithelial tissue, mainly of the respiratory and genitourinary tract, as well as in monocytes, macrophages, and dendritic cells. DEFB1 is a cationic peptide that disrupts the membranes of invading microbes, which are negatively charged due to the presence of lipopolysaccharides (LPS) or lipoteichoic acid (LTA). The primary role of DEFB1 is believed to be prevention of microbial colonization on epithelia. Inhibition of DEFB1 by high salt concentration may play a role in the pathogenesis of cystic fibrosis. DEFB1 is abnormally expressed in Goto-Kakizaki (GK) rats suggesting a role of DEFB1 in diabetic nephropathy.
