Abstract:
This study, reports the identification and analysis of ferritin M chain, from kelp grouper, Epinephelus bruneus (EbFerM); it comprises 1004 base pair (bp), including 528bp open reading frame (ORF) which encodes 176 amino acid (aa) residues; the calculated molecular weight is 20kDa. The 5'-untranslated region (UTR) possesses 476bp proceeded by a putative Iron Regulatory Element (IRE). Pair wise alignments showed that EbFerM shared 94% identity with that of Larimichthys crocea and Sciaenops. It is expressed in abundance in liver, spleen, and kidney when challenged with Vibrio anguillarum, lipopolysaccharide (LPS), or poly I:C.
