Annexin A11 (ANXA11), also known as Annexin XI, 56K Autoantigen and Calcyclin-associated annexin 50 (CAP50), is a 54.4kD (predicted) member of the Annexin protein family. The Annexins are a family of Calcium-dependent phospholipid-binding proteins that are preferentially located on the cytosolic face of the plasma membrane. The Annexin's have a molecular weight of approximately 35-40kD and consist of a unique amino terminal domain followed by a homologous C-terminal core domain containing the calcium-dependent phospholipid-binding sites. The C terminal domain is comprised of four 60-70 amino acid (aa) repeats, known as annexin repeats or an endonexin fold (Annexin A6 contains 8 annexin repeats). The four annexin repeats form a highly -helical, tightly packed disc known as the annexin domain, which binds to phospholipids in the membrane in a calcium-dependent manner. Members of the annexin family play a role in cytoskeletal interactions, phospholipase inhibition, regulation of cellular growth, and intracellular signal transduction pathways. Annexin A11 was identified as a 56 kD antigen recognized by sera from patients with autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, or Sjogren's syndrome. Human Annexin A11 shares 93% identity with mouse and 49% identity with rat Annexin A11.
Western Blot: An antibody concentration of 1.0ug/ml is recommended.
Optimal dilutions should be determined by each laboratory for each application.
Storage and Stability:
Lyophilized powder may be stored at 4°C for short-term only. Reconstitute to nominal volume by adding sterile PBS with 40-50% glycerol and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
