产品介绍background:
This gene encodes a protein that belongs to a family of Ca(2+) dependent phospholipid binding proteins which have a molecular weight of approximately 35,000 to 40,000 and are preferentially located on the cytosolic face of the plasma membrane. Annexin I protein has an apparent relative molecular mass of 40 kDa, with phospholipase A2 inhibitory activity. Since phospholipase A2 is required for the biosynthesis of the potent mediators of inflammation, prostaglandins and leukotrienes, annexin I may have potential anti inflammatory activity.

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.

Subunit:
Homodimer in placenta (20%); linked by transglutamylation. Interacts with DYSF (By similarity).

Subcellular Location:
Nucleus (By similarity). Cytoplasm (By similarity). Cell projection, cilium (By similarity). Basolateral cell membrane (By similarity). Note=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 (By similarity).

Post-translational modifications:
Phosphorylated by protein kinase C, epidermal growth factor receptor/kinase and TRPM7. Phosphorylation results in loss of the inhibitory activity.
