Hepcidin is a cysteine-rich cationic antimicrobial peptide central to iron metabolism. We report a comparative analysis of the sequences, gene organization and expression of two hepcidin genes from olive flounder Paralichthys olivaceus. Both consist of two introns and three exons that encode a prepropeptide (81 amino acids for hepcidin I and 89 amino acids for hepcidin II). A TATA box and several consensus-binding motifs for transcription factors were found upstream of the transcriptional starting site. Hepcidin II was predominantly expressed in the liver and highly inducible under the effect of lipopolysaccharide (LPS), while a large amount of hepcidin I transcripts was detected in various tissues but did not appear to have a significant effect during LPS-stimulation.
