Six antimicrobial peptide genes of the cathelicidin family map to bovine chromosome 22q24 by fluorescence in situ hybridization

Six phage clones containing gene members of the family of antimicrobial peptides named cathelicidins, were mapped to bovine chromosome 22q24, by means of fluorescence in situ hybridization. The mapping data suggest the clustering of cathelicidins into a CATHL@ locus, in a similar manner as for beta-defensins, another family of antimicrobial peptides, defining the locus DEFB@ mapped to 27q13-->q14.
