Interpretive Summary:

Technical Abstract: Annexins, a protein superfamily, are ubiquitous, and play many important roles in immuno-physiological processes. In this report, we cloned and sequenced channel catfish orthologs to human annexin A2, A4, A5 and A11. Total RNA from tissues was extracted and cDNA libraries were constructed by the rapid amplification cDNA end (RACE) method. The gene-specific primers in conjunction with the RACE primers were used to PCR amplify 5’- and 3’-ends of the annexin transcripts. Each annexin nucleic acid sequence had 5’-untranslated region (UTR), an open reading frame (ORF) and 3’-UTR. Each ORF appears to encode 337, 321, 317 and 482 amino acid residues for A2, A4, A5 and A11, respectively. By comparison with the human counterparts, each channel catfish annexin also had four conserved 70 amino-acid-residue repeats. These results provide important information for further elucidating annexin functions in channel catfish.
