Protein attributes
| Sequence length | 346 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| 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 By similarity. |
| Subunit structure | 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. |
| Domain | A pair of annexin repeats may form one binding site for calcium and phospholipid. |
| Post-translational modification | Phosphorylated by protein kinase C, epidermal growth factor receptor/kinase and TRPM7. Phosphorylation results in loss of the inhibitory activity By similarity. |
| Sequence similarities | Belongs to the annexin family. Contains 4 annexin repeats. |
| Caution | Was originally (Ref.1) thought to originate from the sponge Geodia cydonium, but, on the basis of phylogenetic studies (Ref.2) it seems very probable that the DNA sequence coding for this protein comes from a rodent as agreed by the original authors (Ref.3). |
