Members of the annexin family contain 4 internal repeat domains, each of which includes a type II calcium-binding site. The calcium-binding sites are required for annexins to aggregate and cooperatively bind anionic phospholipids and extracellular matrix proteins. The most striking feature of annexin 31 is a complete ablation of all four homologous type II calcium-binding sites in the conserved tetrad core. Althoµgh all 4 type II calcium-binding sites in annexin 31 contained amino acid substitutions that ablated their function, structural analysis sµggests that the conserved putative ion channel formed by the tetrad core is intact. |
