Crystallization and preliminary X-ray crystallographic studies of the sixth PDZ domain of glutamate-receptor interacting protein 1 (GRIP1) from Rattus norvegicus.

Abstract

The sixth PDZ domain from GRIP1 and its complex with the octapeptide of the liprin-alpha1 C-terminus were crystallized at 294 K by the hanging-drop vapour-diffusion method. The native crystal belongs to space group P6(1)22 (or P6(5)22), with unit-cell parameters a = b = 40.3, c = 222.9 A. The complex crystal belongs to space group R32, with unit-cell parameters a = b = 117.8, c = 102.0 A. Native and peptide-complex diffraction data were collected to resolutions of 1.5 and 1.8 A, respectively, using synchrotron X-rays.
