| 中文摘要 | Tumor necrosis factor receptor-associated factor 2 (TRAF2) is a crucial component of almost the entire tumor necrosis factor receptor superfamily signaling pathway. In the present study, a TRAF2 gene has been cloned from grass carp (Ctenopharyngodon idella) by reverse transcription-polymerase chain reaction and rapid amplification of cDNA ends. The full-length cDNA is 3162 bp, including a 60 bp 5' untranslated region (UTR), a 1611 bp open reading frame, and a 1491 bp 3' UTR. The polyadenylation signal (AATAAA) and the mRNA instability motifs (ATTTTA, ATTTA) were followed by a poly(A) tail in the 3' UTR. No signal peptide or transmembrane region has been found in the putative amino acids of grass carp TRAF2 (gcTRAF2). Phylogenetic tree analysis clearly showed that gcTRAF2 is nearest to the TRAF2 gene of goldfish. The identity of gcTRAF2 with its homologs in other vertebrates ranges from 56% to 97%. It is characterized by one RING-type signature at the N-terminus, one zinc finger in the middle part, and one conserved TRAF domain consisting of a C-proximal (TRAF-C) subdomain and a N-proximal (TRAF-N) subdomain. The identity of TRAF-C among all TRAF2 homologs in vertebrates varies from 78% to 97%, whereas the identity of TRAF-N ranges from 56% to 100%. The recombinant gcTRAF2 has been expressed in Escherichia coli using pET-32a expression vector. The rabbit anti-gcTRAF2 polyclonal antibody was obtained. The expression of gcTRAF2 in different organs was examined by real-time quantitative polymerase chain reaction and Western blot analysis. It was widely distributed in heart, head kidney, thymus, brain, gill, liver, spleen, and trunk kidney. This is the first report of a TRAF2 homolog molecule in fish. |
