Target

Full Name
Defensin Alpha 5
Introduction
DEFA5 is highly expressed in the secretory granules of Paneth cells of the ileum. Defensins are a family of antimicrobial and cytotoxic peptides thought to be involved in host defense. They are abundant in the granules of neutrophils and also found in the epithelia of mucosal surfaces such as those of the intestine, respiratory tract, urinary tract, and vagina. Members of the defensin family are highly similar in protein sequence and distinguished by a conserved cysteine motif. Several of the alpha defensin genes appear to be clustered on chromosome 8.
Entrez Gene ID

UniProt ID
Q01523
Alternative Names
Defensin Alpha 5; Defensin, Alpha 5, Paneth Cell-Specific; HD5(20-94); DEF5; Defensin, Alpha 5, Preproprotein; Defensin, Alpha 5; Defensin-5; HD-5;
Function
Has antimicrobial activity against Gram-negative and Gram-positive bacteria. Defensins are thought to kill microbes by permeabilizing their plasma membrane. All DEFA5 peptides exert antimicrobial activities, but their potency is affected by peptide processing.
