N. Khlebtsova et al., Expression, crystallization and preliminary X-ray studies of the PDZ domain of Dishevelled protein, ACT CRYST D, 56, 2000, pp. 212-214
Dishevelled (Dsh) protein is an important component of the Wnt signal-trans
duction pathway. It has three relatively conserved domains: DIX, PDZ and DE
P. The PDZ domain of the Xenopus laevis homolog of Dsh, which consists of r
esidues 254-348, was overexpressed as a soluble protein in Escherichia coli
, purified and crystallized. The crystals were obtained by the vapor-diffus
ion method, using 1.4 M sodium formate as a precipitant. The crystals diffr
acted to 2.3 Angstrom resolution. The space group was determined to be P6(1
)22 or P6(5)22, with unit-cell dimensions a = b = 95.9, c = 93.9 Angstrom.
