Title: Expression, purification, crystallization and preliminary crystallographic study of isolated modules of the mouse coactivator-associated arginine methyltransferase 1

Abstract

Isolated modules of mouse coactivator-associated arginine methyltransferase 1 encompassing the protein arginine N-methyltransferase catalytic domain have been overexpressed, purified and crystallized. X-ray diffraction data have been collected and have enabled determination of the structures by multiple isomorphous replacement using anomalous scattering. Coactivator-associated arginine methyltransferase 1 (CARM1) plays a crucial role in gene expression as a coactivator of several nuclear hormone receptors and also of non-nuclear receptor systems. Its recruitment by the transcriptional machinery induces protein methylation, leading to chromatin remodelling and gene activation. CARM1{sub 28–507} and two structural states of CARM1{sub 140–480} were expressed, purified and crystallized. Crystals of CARM1{sub 28–507} belong to space group P6{sub 2}22, with unit-cell parameters a = b = 136.0, c = 125.3 Å; they diffract to beyond 2.5 Å resolution using synchrotron radiation and contain one monomer in the asymmetric unit. The structure of CARM1{sub 28–507} was solved by multiple isomorphous replacement and anomalous scattering methods. Crystals of apo CARM1{sub 140–480} belong to space group I222, with unit-cell parameters a = 74.6, b = 99.0, c = 207.4 Å; they diffract to beyond 2.7 Å resolution and contain two monomers in the asymmetric unit. Crystals of CARM1{sub 140–480} in complex with S-adenosyl-l-homocysteine belong tomore » space P2{sub 1}2{sub 1}2, with unit-cell parameters a = 74.6, b = 98.65, c = 206.08 Å; they diffract to beyond 2.6 Å resolution and contain four monomers in the asymmetric unit. The structures of apo and holo CARM1{sub 140–480} were solved by molecular-replacement techniques from the structure of CARM1{sub 28–507}.« less

  • The MafB transcription factor (residues 211–305) has been crystallized in complex with the 21 bp Cmare DNA-binding site. Native and mercury-derivatized data collection and preliminary analyses are reported. The MafB transcription factor (residues 211–305) has been overexpressed in and purified from Escherichia coli. A protein–DNA complex between the MafB homodimer and the 21 bp Maf-recognition sequence known as Cmare has been successfully reconstituted in vitro and subsequently crystallized. The diffraction properties of the protein–DNA complex crystals were improved using a combination of protein-construct boundary optimization and targeted mutagenesis to promote crystal lattice stability. Both native and mercury-derivatized crystals have beenmore » prepared using these optimized conditions. The crystals belong to space group P4{sub 1}2{sub 1}2 or P4{sub 3}2{sub 1}2, with unit-cell parameters a = b = 94.8, c = 197.9 Å. An anomalous difference Patterson map computed using data collected from crystals grown in the presence of HgCl{sub 2} reveals four peaks. This corresponds to two copies of the protein–DNA complex in the asymmetric unit, with a solvent content of 62% and a Matthews coefficient of 3.22 Å{sup 3} Da{sup −1}.« less
  • Preliminary X-ray analysis of the proliferation-associated protein Ebp1 from Homo sapiens is provided. ErbB-3-binding protein 1 (Ebp1) is a member of the family of proliferation-associated 2G4 proteins (PA2G4s) and plays a role in cellular growth and differentiation. Ligand-induced activation of the transmembrane receptor ErbB3 leads to dissociation of Ebp1 from the receptor in a phosphorylation-dependent manner. The non-associated protein is involved in transcriptional and translational regulation in the cell. Here, the overexpression, purification, crystallization and preliminary crystallographic studies of Ebp1 from Homo sapiens are reported. Initially observed crystals were improved by serial seeding to single crystals suitable for data collection.more » The optimized crystals belong to the tetragonal space group P4{sub 1}2{sub 1}2 or P4{sub 3}2{sub 1}2 and diffracted to a resolution of 1.6 Å.« less
  • The androgen receptor (AR) is a DNA-binding and hormone-activated transcription factor that plays critical roles in the development and progression of prostate cancer. The transcriptional function of AR is modulated by intermolecular interactions with DNA elements and coactivator proteins, as well as intramolecular interactions between AR domains; thus, the structural information from the full-length AR or a multi-domain fragment is essential for understanding the molecular basis of AR functions. Here we report the expression and purification of full-length AR protein and of a fragment containing its DNA-binding and ligand-binding domains connected by the hinge region in the presence of itsmore » natural ligand, dihydrotestosterone. Crystals of ligand-bound full-length AR and of the AR fragment in complex with DNA elements and coactivator motifs have been obtained and diffracted to low resolutions. These results help establish a foundation for pursuing further crystallographic studies of an AR/DNA complex.« less

  • Crystallization and preliminary crystallographic study of a potential metal-dependent hydrolase with cyclase activity from T. tengcongensis. The putative metal-dependent hydrolase gene TTE1006 from Thermoanaerobacter tengcongensis strain MB4{sup T} (T = type strain; Genbank accession No. AE008691) was heterologously expressed in Escherichia coli. The 205-amino-acid gene product was purified and crystallized. The crystal used for data collection belongs to space group P2{sub 1}, with unit-cell parameters a = 85.2, b = 62.1, c = 172.4 Å, β = 104.2°. Using a synchrotron-radiation source, the resolution limit of the data reached 1.87 Å. Eight molecules were estimated to be present in themore » asymmetric unit, with a solvent content of 48%. Structure determination is ongoing using the multiple-wavelength anomalous diffraction (MAD) method and also the molecular-replacement (MR) method.« less
