The spliceosome consists of five small RNAs and more than 100 proteins. Almost 50% of the human spliceosomal proteins were predicted to be intrinsically disordered or to contain disordered regions, among them the G-patch protein Spp2. The G-patch region of Spp2 binds to the DEAH-box ATPase Prp2, and both proteins together are essential for promoting the transition from the B<sup>act</sup> to the catalytically active B* spliceosome. Here we show by circular dichroism and nuclear magnetic resonanc ...[more]

The catalytic activity of TCPTP is auto-regulated by its intrinsically disordered tail and activated by Integrin alpha-1

Project description:T-Cell Protein Tyrosine Phosphatase (TCPTP, PTPN2) is a non-receptor type protein tyrosine phosphatase that is ubiquitously expressed in human cells. TCPTP is a critical component of a variety of key signaling pathways that are directly associated with the formation of cancer and inflammation. Thus, understanding the molecular mechanism of TCPTP activation and regulation is essential for the development of TCPTP therapeutics. Under basal conditions, TCPTP is largely inactive, although how this is achieved is poorly understood. Thus, in this study we used Intra and inter molecular CX-MS analysis to reveal molecular mechanism of TCPTP activity regulation, our both intra- and inter- molecular CX-MS analysis result shows that the C-terminal intrinsically disordered tail of TCPTP directly bind on the surface of catalytic domain and function as autoinhibitory element to control the TCPTP catalytic activity.

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.

Quantitative cross-linking analysis of chemoresistant HeLa cells

Project description:Chemoresistance is a common mode of therapy failure for many cancers. Tumors develop resistance to chemotherapeutics through a variety of mechanisms, with proteins serving pivotal roles. Changes in protein conformations and interactions affect the cellular response to environmental conditions contributing to the development of new phenotypes. The ability to understand how protein interaction networks adapt to yield new function or alter phenotype is limited by the inability to determine structural and protein interaction changes on a proteomic scale. In this project we combine SILAC with PIR cross-linking technology to generate a quantitative protein interaction map of drug senstive and drug resistant HeLa cells.

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.

Structure of Cyanobacterial Phycobilisome Core Revealed by Structural Modeling and Chemical Cross-linking

Project description:In cyanobacteria and red algae, the structural basis dictating efficient excitation energy transfer from the phycobilisome (PBS) antenna complex to the reaction centers (RCs) remains unclear. PBS has several peripheral rods and a central core, which binds to the thylakoid membrane, allowing energy coupling with Photosystems II (PSII) and Photosystem I (PSI). Here, we integrated chemical cross-linking mass spectrometry with homology modeling analysis to propose a tri-cylindrical cyanobacterial PBS-core structure. Our model reveals a side view crossover configuration of the two basal cylinders, consolidating the essential roles of the anchoring domains comprised of the ApcE PB-loop and ApcD, which facilitate the energy transfer to PSII and PSI respectively. The uneven bottom surface of the PBS-core contrasts with the flat reducing side of PSII. The extra space between two basal cylinders of the PBS-core and PSII provides increased accessibility of regulatory elements, e.g., orange carotenoid protein, which are required for modulating photochemical activities.

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.

Chemical cross-linking mass spectrometry for systems structural biology in mouse heart tissue.

Project description:While modern structural biology technologies have greatly expanded the size and type of protein complexes that can now be studied, the ability to derive large-scale structural information on proteins and complexes as they exist within tissues is practically non-existent. Many protein properties and their involvement in disease pathways are not replicated in cell culture and some complexes are not amenable to purification. Thus, the lack of tissue-level structural information limits molecular-level insight on diseases such as heart failure. Here we demonstrate the application of XL-MS to identify protein structural features and interactions in tissue samples, providing the first systems structural biology insight on protein complexes as they exist in the mouse heart.

The spatial network of skeletal proteins in a stony coral

Project description:Coral skeletons are materials composed of inorganic aragonitic fibers, proteins, sugars and lipids that are highly organized to form a solid body upon which the animals live. The skeleton contains more than 30 proteins, all of which are encoded in the animal genome and secreted during the biomineralization process. How these proteins are spatially related is unknown. Using a combination of chemical crosslinking and high-resolution tandem mass spectrometry, we identify, for the first time. the spatial interactions of the skeletal proteins within a stony coral. Our subsequent network analysis revealed several coral acid-rich proteins (CARPs) are invariably associated with carbonic anhydrase(s), alpha-collagen, cadherins and other calcium binding proteins. These interactions clearly show that protein-protein interactions in coral skeletons are highly coordinated and are key to understanding the formation and persistence of coral skeletons through time
