Crystallization and preliminary X-ray crystallographic analysis of the human CKIP-1 pleckstrin homology domain.

ABSTRACT: The casein kinase 2 interacting protein-1 (CKIP-1) is involved in many cellular functions, including apoptosis, signalling pathways, cell growth, cytoskeleton and bone formation. Its N-terminal pleckstrin homology (PH) domain is thought to play an important role in membrane localization and controls shuttling of CKIP-1 between the plasma membrane and nucleus. In this study, the human CKIP-1 PH domain was purified but problems were encountered with nucleic acid contamination. An S84D/S86D/S88D triple mutant designed to abolish nucleic acid binding was purified and successfully crystallized. Single crystals diffracted to 1.7?Å resolution and belonged to space group P4?2?2 with unit-cell parameters a=53.0, b=53.0, c=113.8?Å, ?=?=?=90.0°.

Crystallization and preliminary X-ray crystallographic analysis of the human kindlin-2 PH domain.

Project description:Kindlins contribute to the correct assembly of integrin-containing focal adhesion sites through their direct interaction with the cytoplasmic tail of ?-integrin. The FERM domain of kindlins has a unique subdomain organization: the F2 subdomain harbours a centrally located pleckstrin homology (PH) domain that is thought to be involved in the membrane targeting of kindlins. FERM domains are found in a number of cytoskeletal proteins that mediate the interaction between integrins and cytosolic proteins. In the present study, the PH domain of human kindlin-2 was subcloned, solubly expressed in Escherichia coli and crystallized using the hanging-drop vapour-diffusion method. A diffraction data set was collected at 2.8?Å resolution using synchrotron radiation on BL-4A at the Pohang Accelerator Laboratory (Pohang, Republic of Korea).

Crystallization and preliminary X-ray crystallographic analysis of human autotaxin.

Project description:Autotaxin (ATX), which is also known as ectonucleotide pyrophosphatase/phosphodiesterase 2 (NPP2 or ENPP2) or phosphodiesterase Iα (PD-Iα), is an extracellular lysophospholipase D which generates lysophosphatidic acid (LPA) from lysophosphatidylcholine (LPC). ATX stimulates tumour-cell migration, angiogenesis and metastasis and is an attractive target for cancer therapy. For crystallographic studies, the α isoform of human ATX was overproduced in Escherichia coli, purified and crystallized using the hanging-drop vapour-diffusion method. X-ray diffraction data were collected to 3.0 Å resolution from a monoclinic crystal form belonging to space group C2, with unit-cell parameters a = 311.4, b = 147.9, c = 176.9 Å, β = 122.6°.

Crystallization and preliminary X-ray crystallographic analysis of the PH-GRAM domain of human MTMR4.

Project description:Phosphoinositide lipid molecules play critical roles in intracellular signalling pathways and are regulated by phospholipases, lipid kinases and phosphatases. In particular, phosphatidylinositol 3-phosphate and phosphatidylinositol 3,5-bisphosphate are related to endosomal trafficking events through the recruitment of effector proteins and are involved in the degradation step of autophagy. Myotubularin-related proteins (MTMRs) are a large family of phosphatases that catalyze the dephosphorylation of phosphatidylinositol 3-phosphate and phosphatidylinositol 3,5-bisphosphate at the D3 position, thereby regulating cellular phosphoinositide levels. In this study, the PH-GRAM domain of human MTMR4 was cloned, overexpressed in Escherichia coli, purified and crystallized by the vapour-diffusion method. The crystals diffracted to 3.20 Å resolution at a synchrotron beamline and belonged to either space group P61 or P65, with unit-cell parameters a = b = 109.10, c = 238.97 Å.

Crystallization and preliminary X-ray crystallographic study of the human MST2 SARAH domain.

Project description:The SARAH domain at the C-terminus of human MST2 (residues 436-484) was overproduced and purified using an Escherichia coli expression system. The purified domain was crystallized using the hanging-drop vapour-diffusion technique. Two crystal forms were obtained.

Crystallization and preliminary X-ray crystallographic analysis of human quinolinate phosphoribosyltransferase.

Project description:Quinolinate phosphoribosyltransferase (QPRTase) is a key NAD-biosynthetic enzyme which catalyzes the transfer of quinolinic acid to 5-phosphoribosyl-1-pyrophosphate, yielding nicotinic acid mononucleotide. Homo sapiens QPRTase (Hs-QPRTase) appeared as a hexamer during purification and the protein was crystallized. Diffraction data were collected and processed at 2.8 Å resolution. Native Hs-QPRTase crystals belonged to space group P2(1), with unit-cell parameters a=76.2, b=137.1, c=92.7 Å, β=103.8°. Assuming the presence of six molecules in the asymmetric unit, the calculated Matthews coefficient is 2.46 Å3 Da(-1), which corresponds to a solvent content of 49.9%.

Crystallization and preliminary crystallographic analysis of human LR11 Vps10p domain.

Project description:Low-density lipoprotein receptor (LDLR) relative with 11 binding repeats (LR11; also known as sorLA) is genetically associated with late-onset Alzheimer's disease and is thought to be involved in neurodegenerative processes. LR11 contains a vacuolar protein-sorting 10 protein (Vps10p) domain. As this domain has been implicated in protein-protein interaction in other receptors, its structure and function are of great biological interest. Human LR11 Vps10p domain was expressed in mammalian cells and the purified protein was crystallized using the hanging-drop vapour-diffusion method. Enzymatic deglycosylation of the sample was critical to obtaining diffraction-quality crystals. Deglycosylated LR11 Vps10p-domain crystals belonged to the hexagonal space group P6(1)22. A diffraction data set was collected to 2.4 Å resolution and a clear molecular-replacement solution was obtained.

Crystallization and preliminary X-ray crystallographic studies of the PYD domain of human NALP3.

Project description:The NALP3 inflammasome is a macromolecular complex that is responsible for the innate immune response against infection by bacterial and viral pathogens. The NALP3 inflammasome is composed of three protein components: NALP3, ASC and caspase 1. Interaction between NALP3 and ASC via PYD domains is critical for the assembly of the NALP3 inflammasome. In this study, human NALP3 PYD, corresponding to amino acids 3-110, was overexpressed in Escherichia coli using engineered C-terminal His tags. NALP3 PYD was then purified to homogeneity and crystallized at 293 K. Finally, X-ray diffraction data were collected to a resolution of 1.7 Å from a crystal belonging to the primitive monoclinic space group P2(1), with unit-cell parameters a = 42.03, b = 60.14, c = 51.61 Å, ? = 107.40°.

Purification, crystallization and preliminary X-ray crystallographic analysis of a central domain of human splicing factor 1.

Project description:Pre-mRNA splicing is an essential source of genetic diversity in eukaryotic organisms. In the early stages of splicing, splicing factor 1 (SF1) recognizes the pre-mRNA splice site as a complex with its partner, U2 auxiliary factor 65 kDa subunit (U2AF(65)). A central `mystery' domain of SF1 (SF1md) lacks detectable homology with known structures, yet is the region of highest phylogenetic sequence conservation among SF1 homologues. Here, steps towards determining the SF1md structure are described. Firstly, SF1md was expressed and purified. The presence of regular secondary structure was verified using circular dichroism spectroscopy and the SF1md protein was then crystallized. A native data set was collected and processed to 2.5 Å resolution. The SF1md crystals belonged to space group C2 and have most probable solvent contents of 64, 52 or 39% with three, four or five molecules per asymmetric unit, respectively. Mutually perpendicular peaks on the κ = 180° section of the self-rotation function support the presence of four molecules in the asymmetric unit.

Expression, purification, crystallization and preliminary X-ray crystallographic analysis of human ?-galactosidase.

Project description:?-D-Galactosidase (?-Gal) is an exoglycosidase that cleaves ?-galactosides from glycoproteins, sphingolipids and keratan sulfate. This study reports the expression, purification, crystallization and preliminary X-ray crystallographic analysis of human lysosomal ?-Gal. The sitting-drop vapour-diffusion method was used to crystallize ?-Gal in complexes with its product galactose and with the inhibitor 1-deoxygalactonojirimycin. The resulting crystals were isomorphous and belonged to space group P2(1). The crystals of the ?-Gal-galactose and the ?-Gal-inhibitor complexes had unit-cell parameters a = 94.8, b = 116.1, c = 140.3 Å, ? = 92.2° and a = 94.8, b = 116.0, c = 140.3 Å, ? = 92.2°, respectively. Diffraction data were collected to 1.8 Å resolution for both crystals.
