Research Abstract

Recently we have discovered a novel Akt binding protein, annexin, which is characterized by Ca2+-dependent interactions with cellular membranes. First we produced cDNA encoding human annexin by PCR with primers corresponding to sequences already reported, using the cDNA library from HEK293 cells and generated recombinant adenovirus to express human annexin. We confirmed the association of annexin with Akt using adenovirus system and then made GST-annexin fusion protein to generate the antibody specific against annexin by immunizing rabbits with this antigen. Fragments of both Akt and annexin were designed by PCR using full-length cDNAs as templates to generate GST-fused proteins.
