ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.



  • Function
    Calcium/phospholipid-binding protein which promotes membrane fusion and is involved in exocytosis. This protein regulates phospholipase A2 activity. It seems to bind from two to four calcium ions with high affinity.
  • Sequence similarities
    Belongs to the annexin family.
    Contains 4 annexin repeats.
  • Domain
    A pair of annexin repeats may form one binding site for calcium and phospholipid.
  • Post-translational
    Phosphorylated by protein kinase C, epidermal growth factor receptor/kinase and TRPM7. Phosphorylation results in loss of the inhibitory activity.
  • Cellular localization
    Nucleus. Cytoplasm. Cell projection > cilium. Basolateral cell membrane. Found in the cilium, nucleus and basolateral cell membrane of ciliated cells in the tracheal endothelium (By similarity). Found in the cytoplasm of type II pneumocytes and alveolar macrophages.
