| Description : |
Beta-defensin 4B is a protein that in humans is encoded by the DEFB4B gene Defensins form a family of microbicidal and cytotoxic peptides made by neutrophils. Members of the defensin family are highly similar in protein sequence. This gene encodes defensin, beta 4B, an antimicrobial peptide implicated in the resistance of epithelial surfaces to microbial colonization. |
