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 projectioncilium 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).
