Abstract: The common carp tumor necrosis factor receptor-associated factor 6 (TRAF6) EST sequence was picked out from the cDNA library of peripheral blood leukocytes that was constructed. The cDNA library were separated from carp and stimulated with mitogen was screened by a probe labeled with DIG. The full-length TRAF6 cDNA was cloned from recombinant phages. Sequence analysis indicated that it encompasses with a 25 bp 5'-UTR and a 535 bp 3'-UTR,the open reading frame (ORF) of which was 1632 bp putatively coding 543 amino acids,and there were two motifs for mRNA instability ATTTA in the 3'-untranslated region. The predicted theoretical isoelectric point and molecular weight were 5.88 and 61.773 ku,respectively. Its nucleotide homology with carp TRAF6 from GenBank was up to 99%.The protein sequence analysis showed that it shared typical sequence features of the TRAF family.
