The amino-terminal region of annexin A2 extends along the concave side of the protein and contains the binding site for the S100A10 (p11) subunit. The interaction of these subunits results in the formation of the heterotetrameric form of the protein, annexin A2-S100A10 heterotetramer (AIIt). To simulate the orientation of AIIt on the plasma membrane we bound AIIt to a phospholipid bilayer that was immobilized on a BIAcore biosensor chip. Surface plasmon resonance was used to observe in real time the molecular interactions between phospholipid-associated AIIt or its annexin A2 subunit and the ligands, tissue-type plasminogen activator (t-PA), plasminogen, and plasmin. AIIt bound t-PA (Kd = 0.68 microm), plasminogen (Kd = 0.11 microm), and plasmin (Kd = 75 nm) with moderate affinity. Contrary to previous reports, the phospholipid-associated annexin A2 subunit failed to bind t-PA or plasminogen but bound plasmin (Kd = 0.78 microm). The S100A10 subunit bound t-PA (Kd = 0.45 microm), plasminogen (Kd = 1.81 microm), and plasmin (Kd = 0.36 microm). Removal of the carboxyl-terminal lysines from the S100A10 subunit attenuated t-PA and plasminogen binding to AIIt. These results show that the carboxyl-terminal lysines of S100A10 form t-PA and plasminogen-binding sites. In contrast, annexin A2 and S100A10 contain distinct binding sites for plasmin."xsd:string |
