Rabbit Anti-DEFb1 (Defensin Beta 1, B-DF1, DEFB1, BD1, DEF-B1, DEFB101, HBD1)
The underlying genes responsible for defensin production are highly polymorphic. Some aspects are conserved, however; the hallmarks of a beta-defensin are its small size, high density of cationic charge and six-cysteine-residue motif. Generally they are encoded by two-exon genes, where the first exon encodes for a hydrophobic leader sequence and the second for a peptide containing the cysteine motif. There are three main (known) forms of mammalian defensins; alpha-defensins, beta-defensins, and theta-defensins. It is theorised that some of the pathology of cystic fibrosis arises from the inhibition of beta-defensin activity on the epithelial surfaces of the lungs and trachea due to higher salt content.
