| Abstract: | With the approaches of cDNA library, RACE, fluorescent real-time quantitative PCR and western blot, the full-length ferritin cDNA was identified and characterized in South cultured Stichopus japonicus (denoted as SjFER) in the present study. All these results indicated: 1) The cDNA of SjFER was of 1222bp, consisting of a 5'UTR of 513bp with a putative iron regulatory element (IRE), a 3'UTR of 187bp, and a complete open reading frame of 522bp encoding a polypeptide with 173 amino acid residues. The conserved motifs for ferritin including iron binding signature, H-specific ferroxidase center and phosphorylation site were totally found in the deduced amino acid of SjFER. 2) SjFER was an important molecule in the species environmental adaption. The expression level of SjFER in South sea cucumber was two times higher than that from North in the tissue of muscle, while no difference occurred in tissue of respiratory tree. 3) The ployclonal antibodies generated from the recombinant product of SjFER could be specifically identified not only the recombinant product, but also the native protein from muscles, and should be used for next functional validation. |
