Recombinant Human beta-Defensin 1/DEFB1

Source: E.coli. MW :5.07kD. Recombinant Human beta-Defensin 1 is produced by our E.coli expression system and the target gene encoding Gly22-Lys68 is expressed. beta-Defensin 1 (DEFB1) is a member of the beta-defensin family, which is highly expressed by epithelial cells. beta-defensins are expressed as the C-terminal portion of precursors and are released by proteolytic cleavage of a signal peptide. beta-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds. beta-defensin 1 is an antimicrobial peptide implicated in the resistance of epithelial surfaces to microbial colonization. Defects in beta-Defensin-1 contribute to asthma diagnosis, with apparent gender-specific effects in human. beta-defensin 1 may also play a role in the pathogenesis of severe sepsis. In addition, beta-defensin 1 is associated with induction profiles in gingival keratinocytes. Protein function: Has bactericidal activity. May act as a ligand for C-C chemokine receptor CCR6. Positively regulates the sperm motility and bactericidal activity in a CCR6-dependent manner. Binds to CCR6 and triggers Ca2+ mobilization in the sperm which is important for its motility (PubMed:25122636). [The UniProt Consortium]
