Cloning, purification and crystallization of full-length human annexin 2.

Annexin 2, a Ca(2+)/phospholipid-binding protein, is involved in many biological processes, including membrane aggregation and the modulation of fibrinolytic activity. Here, the expression and purification of recombinant full-length human annexin 2 is reported, as well as crystals obtained by sitting-drop and hanging-drop vapor diffusion at 277 K. A condition consisting of 18% PEG 8000, 0.
