DEFB118 Recombinant Protein

Source : Escherichia Coli. DEFB118 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 126 amino acids (21-123 a.a) and having a molecular mass of 13.8kDa.DEFB118 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Beta Defensin 118 (DEFB118) which is a member of the beta subfamily of defensins, is found in a cluster with other beta-defensin genes on the long arm of chromosome 20. Beta-defensins are antimicrobial peptides which provide protection for tissues and organs from infection by a diversity of microorganisms. DEFB118 protein's expression is regulated by androgen, and the encoded protein binds to sperm and exhibits antibacterial activity.
