Background: beta-Defensin 2

Human BD-2, also known as defensin beta 2 (DEFB-2), is a secreted, 41 amino acid residue anti-microbial protein belonging to the defensin family. Mature defensins are cationic proteins with three intramolecular disulfides and a characteristic triple-stranded beta -sheet. Human BD-2 expression is induced by inflammatory signals in multiple tissues, including airway epithelial cells and keratinocytes. At the amino acid sequence level, human BD-2 shares 98% and 51% homology with the proteins from rhesus monkey and rat, respectively.
