Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 35 kDa (predicted molecular weight: 39 kDa).
  • Application notes
    Is unsuitable for Flow Cyt,ICC/IF,IHC-P or IP.
  • Target

    • 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.

      Lanes 1 - 3: Merged signal (red and green). Green - ab138512 observed at 40 kDa. Red - loading control, ab18058, observed at 130 kDa.


      ab138512 was shown to specifically react with Annexin I when Annexin I knockout samples were used. Wild-type and Annexin I knockout samples were subjected to SDS-PAGE. Ab138512 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
