Crystallographic characterization of the membrane-binding domain of radixin

Radixin is a protein which cross-links plasma membranes and actin filaments and thus forms membrane-associated cytoskeleton. The radixin N-terminal do main, which is responsible for membrane association, has been purified and crystallized by vapour diffusion with polyethylene glycol 6000. The crystal s belong to space group P4(1)2(1)2 or P4(3)2(1)2, with unit-cell parameters a = b = 96.36, c = 133.16 Angstrom, and diffract to a resolution of 3.0 An gstrom.
