Gene ID: 1673 | Gene type: protein coding

About DEFB4A

Cytogenetic location: 8p23.1 Genomic coordinates (GRCh38): 8:7,894,677-7,896,716 (from NCBI)

This gene has 1 transcript (splice variant), 1 gene allele, 8 orthologues and 3 paralogues. Biased expression in gall bladder (RPKM 1.2), esophagus (RPKM 0.7) and 3 other tissues.

Summary

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 4, an Antibiotic peptide which is locally regulated by inflammation. [provided by RefSeq, Jul 2008]
