Summary	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. The protein encoded by this gene, defensin, alpha 1, is found in the microbicidal granules of neutrophils and likely plays a role in phagocyte-mediated host defense. Several alpha defensin genes are clustered on chromosome 8. This gene differs from defensin, alpha 3 by only one amino acid. This gene and the gene encoding defensin, alpha 3 are both subject to copy number variation. Two transcript variants encoding different isoforms have been found for this gene.

** You may select a custom vector to replace pcDNA3.1+/C-(K)DYK after clone is added to cart.

** GenScript guarantees 100% sequence accuracy of all synthetic DNA constructs we deliver, but we do not guarantee protein expression in your experimental system. Protein expression is influenced by many factors that may vary between experiments or laboratories. In addition, please pay attention to the signal peptide, propeptide and transit peptide in target ORF, which may affect the choice of vector (N/C terminal tag vector).

***One clone ID might be correlated to multiple accession numbers, which share the same CDS sequence.

Transcript Variant: This variant (2) lacks an alternate exon in the 5' coding region and initiates translation at a downstream start site compared to variant 1. The resulting isoform (2) is shorter at the N-terminus compared to isoform 1. Publication Note: This RefSeq record includes a subset of the publications that are available for this gene.
