Crystallization and preliminary X-ray analysis of human Brn-5 transcription factor in complex with DNA.

ABSTRACT: The Brn-5 protein plays an important role in the control of cellular development and belongs to a class of transcription factors that usually contain two domains: the POU homeodomain (POU(HD)) and the POU-specific domain (POU(S)). Since high-quality crystals suitable for crystallographic studies of the proteins of this class are difficult to obtain, all the known structural information available is for POU(HD) and/or POU(S). This paper describes several critical steps that allowed the production of high-quality crystals of the full-length Brn-5 protein complexed with its cognate DNA.

Preparation, crystallization and preliminary X-ray diffraction analysis of the DNA-binding domain of the Ets transcription factor in complex with target DNA.

Project description:The Ets2 transcription factor is a member of the Ets transcription-factor family. Ets2 plays a role in the malignancy of cancer and in Down's syndrome by regulating the transcription of various genes. The DNA-binding domain of Ets2 (Ets domain; ETSD), which contains residues that are highly conserved among Ets transcription-factor family members, was expressed as a GST-fusion protein. The aggregation of ETSD produced after thrombin cleavage could be prevented by treatment with NDSB-195 (nondetergent sulfobetaine 195). ETSD was crystallized in complex with DNA containing the Ets2 target sequence (GGAA) by the hanging-drop vapour-diffusion method. The best crystals were grown using 25% PEG 3350, 80 mM magnesium acetate, 50 mM sodium cacodylate pH 5.0/5.5 as the reservoir at 293 K. The crystals belonged to space group C2, with unit-cell parameters a = 85.89, b = 95.52, c = 71.89 A, beta = 101.7 degrees and a V(M) value of 3.56 A(3) Da(-1). Diffraction data were collected to a resolution of 3.0 A.

Crystallization and preliminary X-ray diffraction analysis of the human XRCC4-XLF complex.

Project description:XRCC4 and XLF are key proteins in the repair of DNA double-strand breaks through nonhomologous end-joining. Together, they form a complex that stimulates the ligation of double-strand breaks. Owing to the suggested filamentous nature of this complex, structural studies via X-ray crystallography have proven difficult. Multiple truncations of the XLF and XRCC4 proteins were cocrystallized, but yielded low-resolution diffraction (~20 Å). However, a combination of microseeding, dehydration and heavy metals improved the diffraction of XRCC4(?157)-XLF(?224) crystals to 3.9 Å resolution. Although molecular replacement alone was unable to produce a solution, when combined with the anomalous signal from tantalum bromide clusters initial phasing was successfully obtained.

Crystallization and preliminary X-ray crystallographic analysis of sterol transcription factor Upc2 from Saccharomyces cerevisiae.

Project description:Upc2, a zinc-cluster transcription factor, is a regulator of ergosterol biosynthesis in yeast. In response to sterol levels, the transcriptional activity of Upc2 is controlled by the C-terminal domain. In this study, the C-terminal regulatory domain of Upc2 from Saccharomyces cerevisiae was purified and crystallized by the vapour-diffusion method. To improve the diffraction quality of Upc2 crystals, a Upc2 fusion protein in which 11 residues of the variable loop (residues 715-725) were replaced by T4 lysozymes in Upc2 (Upc2-T4L) was engineered. The Upc2-T4L crystals diffracted to 2.9 Å resolution using synchrotron radiation. The crystal was trigonal, belonging to space group P3(2) with unit-cell parameters a = 67.2, b = 67.2, c = 257.5 Å. The Matthews coefficient was determined to be 3.41 Å(3) Da(-1) with two molecules in the asymmetric unit. Initial attempts to solve the structure by the single-anomalous dispersion technique using selenomethionine were successful.

Crystallization and preliminary X-ray crystallographic analysis of human plasma platelet activating factor acetylhydrolase.

Project description:The plasma form of the human enzyme platelet activating factor acetylhydrolase (PAF-AH) has been crystallized, and X-ray diffraction data were collected at a synchrotron source to a resolution of 1.47 A. The crystals belong to space group C2, with unit cell parameters of a = 116.18, b = 83.06, c = 96.71 A, and beta= 115.09 degrees and two molecules in the asymmetric unit. PAF-AH functions as a general anti-inflammatory scavenger by reducing the levels of the signaling molecule PAF. Additionally, the LDL bound enzyme has been linked to atherosclerosis due to its hydrolytic activities of pro-inflammatory agents, such as sn-2 oxidatively fragmented phospholipids.

Complex assembly, crystallization and preliminary X-ray crystallographic analysis of the human Rod-Zwilch-ZW10 (RZZ) complex.

Project description:The spindle-assembly checkpoint (SAC) monitors kinetochore-microtubule attachment during mitosis. In metazoans, the three-subunit Rod-Zwilch-ZW10 (RZZ) complex is a crucial SAC component that interacts with additional SAC-activating and SAC-silencing components, including the Mad1-Mad2 complex and cytoplasmic dynein. The RZZ complex contains two copies of each subunit and has a predicted molecular mass of ∼800 kDa. Given the low abundance of the RZZ complex in natural sources, its recombinant reconstitution was attempted by co-expression of its subunits in insect cells. The RZZ complex was purified to homogeneity and subjected to systematic crystallization attempts. Initial crystals containing the entire RZZ complex were obtained using the sitting-drop method and were subjected to optimization to improve the diffraction resolution limit. The crystals belonged to space group P3₁ (No. 144) or P3₂ (No. 145), with unit-cell parameters a = b = 215.45, c = 458.7 Å, α = β = 90.0, γ = 120.0°.

Crystallization and preliminary X-ray diffraction analysis of human importin ?-Snail zinc finger domain complex.

Project description:Snail is a C2H2-type zinc finger transcriptional repressor that induces epithelial-mesenchymal transition by repression of E-cadherin expression levels during embryonic development and tumour progression. Snail is imported into the nucleus by importin ? through direct binding with its four zinc finger domain. The complex between importin ? and Snail four zinc finger domain was crystallized in order to understand the nuclear transport mechanism of Snail. The constituents of the complex were separately expressed and were then co-purified and crystallized by the hanging-drop vapour-diffusion method. The crystals belonged to space group C2, with unit-cell parameters a = 228.2, b = 77.5, c = 72.0?Å, ? = 100.9° and diffracted to 2.5?Å resolution.

Crystallization and preliminary X-ray analysis of the tumour necrosis factor alpha-tumour necrosis factor receptor type 2 complex.

Project description:Tumour necrosis factor receptor type 2 (TNFR2, TNFRSF1B) is an essential receptor for various host-defence functions of tumour necrosis factor alpha (TNF). As part of studies to determine the structure of TNFR2, the formation, crystallization and preliminary X-ray diffraction analysis of the TNF-TNFR2 complex are described. The TNF-TNFR2 complex, which comprises one TNF trimer and three TNFR2 monomers, was confirmed and purified by size-exclusion chromatography. Crystals of the TNF-TNFR2 complex were obtained using polyethylene glycol 3350 as a precipitant. The crystal belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 74.5, b = 117.4, c = 246.8 A. Assuming the presence of two TNF-TNFR2 complexes in the asymmetric unit, the Matthews coefficient V(M) was 2.49 A(3) Da(-1) and the solvent content of the crystal was 50.7%. The crystal diffracted to 2.95 A resolution.
