Crystallization and preliminary X-ray crystallographic studies of the CIDE-N domain of CIDE-3

초록

The CIDE-3 protein plays a critical role in lipid metabolism by its involvement in lipid droplet formation. CIDE-3 contains two conserved cell-death-inducing DFF45-like effector (CIDE) domains (CIDE-N at the N-terminus and CIDE-C at the C-terminus) of ∼90 amino-acid residues that are involved in protein–protein interaction. In this study, the CIDE-N domain of CIDE-3 was purified and crystallized by the hanging-drop vapour-diffusion method and X-ray diffraction data were collected from the crystals to a resolution of 2.0 Å. The crystals were found to belong to space group P32, with unit-cell parameters a = b = 63.35, c = 37.60 Å, γ = 120°.
