Domain (CC)
The full-length protein can bind eight Ca(2+) ions via the annexin repeats. Calcium binding causes a major conformation change that modifies dimer contacts and leads to surface exposure of the N-terminal phosphorylation sites; in the absence of Ca(2+), these sites are buried in the interior of the protein core. The N-terminal region becomes disordered in response to calcium-binding.
