Recombinant Human BD-1 (36 a.a.)





 





		Synonyms :
beta-Defensin 1



		Description :
Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system.  The α-defensins are distinguished from the β-defensins by the pairing of their three disulfide bonds.  To date, four human β-defensins have been identified; BD-1, BD-2, BD-3 and BD-4.  β-defensins are expressed on some leukocytes and at epithelial surfaces.  In addition to their direct antimicrobial activities, they are chemoattractant towards immature dendritic cells and memory T cells.  The β-defensin proteins are expressed as the C-terminal portion of precursors and are released by proteolytic cleavage of a signal sequence and, in the case of BD-1 (36 a.a.), a propeptide region.  β-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds.  β-Defensins are 3-5 kDa peptides ranging in size from 33-47 amino acid residues.  Recombinant Human BD-1 is a 3.9 kDa protein containing 36 amino acid residues.
