AbstractThioredoxin (abbreviated as Trx) is an important ubiquitous disulfide reductase, which can protect organisms against various oxidative stresses. In the present study, a thioredoxin-related protein of 14 kDa (named as Ec-TRP14) was identified from the marine fish grouper, Epinephelus coloides by RACE PCR. The full-length cDNA of Ec-TRP14 was comprised of 1066 bp with a 372 bp open reading frame that encodes a putative protein of 123 amino acids. Similar to most TRP145, Ec-TRP14 contained the conserved motif C-P-D-C. Ec-TRP14 mRNA is predominately expressed in liver, brain and muscle. The expression of Ec-TRP14 was up-regulated in the liver of grouper challenged with SGIV. Ec-TRP14 was recombined and expressed in Escherichia call BL21 (DE3), and the rEc-Ec-TRP14 fusion protein was demonstrated to possess the antioxidant activity. The grouper spleen (GS) cells were treated with a high concentration of rEc-TRP14 (8.3 mu g/ml), which significantly enhanced cells viability under damage caused by viral infection. These results together indicated that Ec-TRP14 could function as an important antioxidant in a physiological context, and might be involved in the responses to viral challenge. (C) 2013 Elsevier Ltd.
