Kinetochores are supramolecular assemblies that link centromeres to microtubules for sister chromatid segregation in mitosis. For this, the inner kinetochore CCAN/Ctf19 complex binds to centromeric chromatin containing the histone variant CENP-A, but whether the interaction of kinetochore components to centromeric nucleosomes is regulated by posttranslational modifications is unknown. Here, we investigated how methylation of arginine 37 (R37Me) and acetylation of lysine 49 (K49Ac) on the CENP-A ...[more]

Structure of the Fanconi anaemia monoubiquitin ligase complex

Project description:The Fanconi Anemia (FA) pathway repairs DNA damage caused by endogenous and chemotherapy-induced DNA crosslinks. Genetic inactivation of this pathway impairs development, prevents blood production and promotes cancer. The key molecular step in the FA pathway is the monoubiquitination of a heterodimer of FANCI-FANCD2 by the FA core complex - a megadalton multiprotein E3 ubiquitin ligase. Monoubiquitinated FANCI-FANCD2 then activates a pathway to remove the DNA crosslink. Lack of molecular insight into the FA core complex limits a detailed explanation of how this vital DNA repair pathway functions. Here we reconstituted an active, recombinant FA core complex, and used electron cryo-microscopy (cryo-EM) and mass spectrometry to determine its overall structure. The FA core complex is comprised of a central symmetric dimer of the FANCB and FAAP100 subunits, flanked by two copies of the RING finger protein, FANCL. This acts as a scaffold to assemble the remaining five subunits, resulting in an extended asymmetric structure. The two FANCL subunits are positioned at opposite ends of the complex in an unusual asymmetric arrangement, distinct from other E3 ligases. We propose that each of the two FANCL subunits play unique roles within the complex – one is a structural component while the other monoubiquitinates FANCD2. The cryo-EM structure of the FA core complex, supported by crosslinking mass spectrometry and native mass spectrometry, therefore provides a foundation for a detailed understanding of this fundamental DNA repair pathway.

A model dataset for quantitative cross-linking/mass spectrometry using isotope-labeled cross-linkers

Project description:Dynamic proteins and multi-protein complexes govern most biological processes. Cross-linking/mass spectrometry (CLMS) is increasingly successful in providing residue-resolution data on static proteinaceous structures. In order to investigate the technical feasibility of recording dynamic processes using isotope-labelling for quantitation, we generated a model dataset by cross-linking human serum albumin (HSA) with the readily available cross-linker BS3-d0/d4 in different heavy/light ratios.

Aurora B kinase disrupts the extended conformation of lattice-bound Kinesin-13 MCAK

Project description:We reveal that MCAK has a compact conformation in solution using cross-linking and electron microscopy. When MCAK is bound to the microtubule ends, it adopts an extended conformation with the N terminus and neck region of MCAK interacting with the microtubule. Also Aurora Bphosphorylation does not alter MCAK conformation in solution. Aurora B interferes with the extended conformation of MCAK on microtubules to decrease the affinity of MCAK for microtubules and reduces its depolymerase activity in a graded fashion.

Quantitative cross-linking/mass spectrometry reveals subtle protein conformational changes

Project description:We have developed quantitative cross-linking/mass spectrometry (QCLMS) to interrogate conformational rearrangements of proteins in solution. Our workflow was tested using a structurally well-described reference system, the human complement protein C3 and its activated cleavage product C3b. We found that small local conformational changes affect the yields of cross-linking residues that are near in space while larger conformational changes affect the detectability of cross-links. Distinguishing between minor and major changes required robust analysis based on replica analysis and a label-swapping procedure. By providing workflow, code of practice and a framework for semi-automated data processing, we lay the foundation for QCLMS as a tool to monitor the domain choreography that drives binary switching in many protein-protein interaction networks.

Pre-40S ribosome biogenesis factor Tsr1 is an inactive structural mimic of translational GTPases

Project description:Budding yeast Tsr1 is an essential ribosome biogenesis factor that is required for cytoplasmic steps in 40S subunit maturation. S. cerevisiae Tsr1 was expressed as an N-terminal GST fusion protein in E. coli. A mutant Tsr1ΔNΔloop was generated in which residues 410 to 476 of Tsr1 were replaced with a short glycine and serine rich sequence; in addition, the N-ternimal 45 amino acid residues were replaced by five amino acid residues “GPDSD”. Tsr1ΔNΔloop allowed for generating native crystals that diffracted to 3.6 Å. Here we characterize both wild type Tsr1 and Tsr1ΔNΔloop using cross-linking/mass spectrometry.

Quantitative cross-linking/mass spectrometry analysis revealed unknown structure of complement iC3

Project description:We applied quantitative cross-linking/mass spectrometry (QCLMS) to interrogate the structure of iC3 (or C3(H2O)), the activated hydrolytic product of the abundant human complement protein C3. The slow but spontaneous and ubiquitous formation of iC3 from C3 initiates antibody-independent activation of the complement system that is a key first line of antimicrobial defense. QCLMS revealed structural differences and similarities between iC3 and C3, as well as between iC3 and C3b that is a pivotal proteolytic cleavage product of C3 and is functionally similar to iC3. Considered in combination with the crystal structures of C3 and C3b, our data support a model wherein the thioester-containing domain of C3 swings to the other end of the molecule creating, in iC3, a stable C3b-like platform for binding the zymogen, factor B, or the regulator, factor H. The integration of available crystallographic and QCLMS data allowed the determination of a 3D model for iC3. The unique arrangement of domains in iC3, which retains the anaphylatoxin (ANA) domain (while ANA is excised when C3 is enzymatically activated to C3b), is consistent with observed differences in activation and regulation between iC3 and C3b.

3D topology of the SMC2/SMC4 sub-complex from chicken condensin I revealed by cross-linking and molecular modelling

Project description:SMC proteins are essential components of three protein complexes that are important for chromosome structure and function. The cohesin complex holds replicated sister chromatids together, whereas the condensin complex has an essential role in mitotic chromosome architecture. Both are involved in interphase genome organisation. SMC-containing complexes are large (>650 kDa for condensin) and contain long anti-parallel coiled-coils. They are thus difficult subjects for conventional crystallographic and electron cryomicroscopic studies. Here we have used amino acid-selective cross-linking and mass spectrometry (CLMS) combined with structure prediction to develop a full-length molecular draft 3D-structure of the SMC2/SMC4 dimeric backbone of chicken condensin. We assembled homology-based molecular models of the globular heads and hinges with the lengthy coiled-coils modelled in fragments, using numerous high-confidence cross-links and accounting for potential irregularity. Our experiments reveal that isolated condensin complexes can exist with their coiled-coil segments closely apposed to one another along their lengths and define the relative spatial alignment of the two anti-parallel coils. The centres of the coiled-coils can also approach one another closely in situ in mitotic chromosomes. In addition to revealing structural information, our cross-linking data suggest that both H2A and H4 may have roles in condensin interactions with chromatin.

An integrated workflow for cross-linking/mass spectrometry

Project description:We present a concise workflow to enhance the mass spectrometric detection of cross-linked peptides by introducing sequential digestion and the database search software Xi. We use sequential digestion to reduce the peptide size and increase identification rates. The methodology is independent of samples complexity, cross-linker choice, method acquisition and can be used with multiple digestion steps.

A folded conformation of MukBEF and Cohesin

Project description:Structural maintenance of chromosomes (SMC)-kleisin complexes organize chromosomal DNAs in all domains of life, where they have key roles in chromosome segregation, DNA repair and regulation of gene expression. They function through topological entrapment and active translocation of DNA, but the underlying conformational changes are largely unclear. Using structural biology, mass spectrometry and cross-linking, we investigated the architecture of two evolutionarily distant SMC-kleisin complexes: proteobacterial MukBEF and eukaryotic cohesin. We show that both contain a dynamic coiled-coil discontinuity, the elbow, near the middle of their arms that permits a folded conformation. Bending at the elbow brings into proximity the hinge dimerization domain and the head/kleisin module, situated at opposite ends of the arms. Our findings favor SMC activity models that include a large conformational change in the arms, such as a relative movement between DNA binding sites during DNA loading and translocation
