Figure 9. Model of annexin A6–mediated membrane repair in skeletal muscle, cardiomyocytes, and neurons.

Figure 9

Upon plasma membrane breach, extracellular Ca2+ enters the damaged cell. Annexin A6 (A6) binds Ca2+, translocates to the site of membrane injury targeting exposed phospholipids such as PS, and forms a repair cap at the lesion. Extracellular recombinant annexin A6 (rA6) localizes to the repair cap at the site of injury, enhancing repair capacity.
