Function of hepcidin
WebIt functions as a BMP co-receptor activating hepcidin expression through a BMP/SMAD signaling pathway. 44 In addition to residing on the cell membrane, part of Hjv can be cleaved and secreted in a soluble form present in blood. sHjv can selectively bind to BMP ligands and inhibit endogenous and BMP-induced hepcidin expression. WebTherefore, the purposes of this research were to overexpress and structurally analyze Nile tilapia hepcidin ( On -Hep), as both a propeptide and a mature peptide, and to determine their antibacterial activities against pathogenic bacteria. Transcriptional level expression of On -Hep was quantitatively analyzed under pathogenic bacterial infection.
