CDNA cloning and expression characterization of serum transferrin gene from oriental weatherfish Misgurnus anguillicaudatus. Issue 4 (12th February 2014) - Chen, J. H.
Abstract In this study, the cDNA coding serum transferrin (stf) of Misgurnus anguillicaudatus (mastf) was cloned. mastf cDNA is composed of 2326 bp with a 2007 bp open reading frame encoding 668 amino acids. The deduced Mastf protein consists of a signal peptide, two lobes (N and C‐lobes) and signature motifs of transferrin (Tf) family. The results of tissue distribution indicated that mastf mRNA was predominantly expressed in the liver. The results indicate that the mastf expression increased significantly in liver, blood, spleen and head kidney after the challenge with Aeromonas sobria, acting as a positive acute protein, suggesting that mastf is related to the immune response. The cloning and expression analysis of mastf further demonstrates the evolutionary conservation of Stf and immune function in vertebrates.
