  • FunctionCalcium/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 similaritiesBelongs to the annexin family.
    Contains 4 annexin repeats.
  • DomainA 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 localizationNucleus. 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.

  • ab2487, staining Annexin A1 (green) in and sub-acutely injured equine superficial digital flexor tendons by Immunohistochemistry (Frozen sections).

    After warming cryosections at room temperature for 30 minutes, sections were rehydrated in 1% PBS-Tween 20 (PBS-T) and blocked in PBS containing 5% normal goat serum for 1 hour at room temperature. Sections were incubated with the primary antibody (1/100 in PBS + 5% normal goat serum) for 2 hours. An AlexaFluor®488-conjugated goat anti-mouse IgG was used as the secondary antibody (1/300).
