Annexins are Ca2+-dependent phospholipid-binding proteins. They are ubiquitous in living organisms and are involved in many cellular processes. In the course of studying Edwardsiella ictaluri pathogenesis in channel catfish, we identified that six annexin expressed sequence tags (A1, A2, A4, A5, A6 and A11) were up-regulated at the early stage of infection. In this study, we cloned and characte...
