dc.description.abstract <p>Antimicrobial peptides (AMP) are important elements of the first line of defence against pathogens in animals. NK-lysin is a cationic AMP that plays a critical role in innate immunity. The chicken <em>NK-lysin</em> gene has been cloned and its antimicrobial and anticancer activity has been described but its location in the chicken genome remains unknown. Here, we mapped the <em>NK-lysin</em> gene and examined the distribution of a functionally significant single nucleotide polymorphism (SNP) among different chicken inbred lines and heritage breeds. A 6000 rad radiation hybrid panel (ChickRH6) was used to map the <em>NK-lysin</em> gene to the distal end of chromosome 22. Two additional genes, the <em>adipocyte enhancer-binding protein 1-lik</em>e gene (<em>AEBP1</em>) and the <em>DNA polymerase delta subunit 2-like</em> (<em>POLD2</em>) gene, are located in the same NW_003779909 contig as <em>NK-lysin</em>, and were thus indirectly mapped to chromosome 22 as well. Previously, we reported a functionally significant SNP at position 271 of the <em>NK-lysin</em> coding sequence in two different chicken breeds. Here, we examined this SNP and found that the A allele appears to be more common than the G allele in these heritage breeds and inbred lines. The chicken <em>NK-lysin</em> gene mapped to the distal end of chromosome 22. Two additional genes,<em>AEBP1</em> and <em>POLD2</em>, were indirectly mapped to chromosome 22 also. SNP analyses revealed that the A allele, which encodes a peptide with a higher antimicrobial activity, is more common than the G allele in our tested inbred lines and heritage breeds.</p>
