Andrew Hinck’s research is focused on using the tools of structural biology to understand how the structure and dynamics of biological macromolecules engenders them with their extraordinary ability to specifically and seletively bind relevant partners and assemble into functional complexes. In my laboratory, we rely heavily on NMR spectroscopy as a tool for studying the structure and dynamics of biological macromolecules, but we also use X-ray crystallography and other accompanying biophysical tools, such as isothermal titration calorimetry (ITC), surface plasmon resonance (SPR), and fluorescence spectroscopy. In addition, my laboratory employs cell-based studies to assess the significance of key molecular features we have identified in a cellular context. In my laboratory, a major area of emphasis is studying signaling proteins and receptors of the TGF-beta family, a highly diversified signaling family, with representative family members in both in invertebrates and vertebrates. In our research, we are interested in deciphering the molecular adaptations that the signaling proteins, single-pass transmembrane receptors, downstream effectors, and multitude of extracellular and intracellular modulators have acquired that enable the more than thirty proteins of family to achieve their unique biological functions. In addition, we are interested in exploiting the unique adaptations our structural studies uncovered to develop highly potent TGF-beta inhibitors for treatment of cancer or fibrosis.

Pitt-led Team Describes Molecular Detail of HIV’s Inner Coat, Pointing the Way to New Therapies

PITTSBURGH, May 29, 2013 – A team led by researchers at the University of Pittsburgh School of Medicine has described for the first time the 4-million-atom structure of the HIV’s capsid, or protein shell. The findings, highlighted on the cover of the May 30 issue of Nature, could lead to new ways of fending off an often-changing virus that has been very hard to conquer.
Scientists have long struggled to decipher how the HIV capsid shell is chemically put together, said senior author Peijun Zhang, Ph.D., associate professor, Department of Structural Biology, University of Pittsburgh School of Medicine.
“The capsid is critically important for HIV replication, so knowing its structure in detail could lead us to new drugs that can treat or prevent the infection,” she said. “This approach has the potential to be a powerful alternative to our current HIV therapies, which work by targeting certain enzymes, but drug resistance is an enormous challenge due to the virus’ high mutation rate.”
Previous research has shown that the cone-shaped shell is composed of identical capsid proteins linked together in a complex lattice of about 200 hexamers and 12 pentamers, Dr. Zhang said. But the shell is non-uniform and asymmetrical; uncertainty remained about the exact number of proteins involved and how the hexagons of six protein subunits and pentagons of five subunits are joined. Standard structural biology methods to decipher the molecular architecture were insufficient because they rely on averaged data, collected on samples of pieces of the highly variable capsid to identify how these pieces tend to go together.
Instead, the team used a hybrid approach, taking data from cryo-electron microscopy at an 8-angstrom resolution (a hydrogen atom measures 0.25 angstrom) to uncover how the hexamers are connected, and cryo-electron tomography of native HIV-1 cores, isolated from virions, to join the pieces of the puzzle. Collaborators at the University of Illinois then used their new Blue Waters supercomputer to run simulations at the petascale, involving 1 quadrillion operations per second, that positioned 1,300 proteins into a whole that reflected the capsid’s known physical and structural characteristics.
The process revealed a three-helix bundle with critical molecular interactions at the seams of the capsid, areas that are necessary for the shell’s assembly and stability, which represent vulnerabilities in the protective coat of the viral genome.
“The capsid is very sensitive to mutation, so if we can disrupt those interfaces, we could interfere with capsid function,” Dr. Zhang said. “The capsid has to remain intact to protect the HIV genome and get it into the human cell, but once inside it has to come apart to release its content so that the virus can replicate. Developing drugs that cause capsid dysfunction by preventing its assembly or disassembly might stop the virus from reproducing.”
The project was funded by National Institutes of Health grants GM082251, GM085043 and GM104601 and the National Science Foundation.
“By using a combination of experimental and computational approaches, this team of investigators has produced a clearer picture of the structure of HIV’s protective covering,” said the National Institutes of Health’s Michael Sakalian, Ph.D., who oversees this and other grants funded through an AIDS-related structural biology program. “The new structural details may reveal vulnerabilities that could be exploited by future therapeutics.”

EAS New Faculty Award in NMR Spectroscopy

 

Patrick van der Wel is an assistant professor in the Department of Structural Biology of the University of Pittsburgh School of Medicine.  He received his undergraduate degree in Chemistry at Utrecht University in the Netherlands, and his PhD degree in Chemistry & Biochemistry at the University of Arkansas, in Fayetteville.  He then pursued his postdoctoral research in the lab of Professor Robert Griffin at the Massachusetts Institute of Technology, before joining the faculty of the University of Pittsburgh in 2008.

Dr. van der Wel’s scientific interests focus on the development and application of solid-state NMR spectroscopy for studies of biological systems.  During his undergraduate and graduate research, he applied solid-state NMR to address basic biophysical and structural processes that govern protein-lipid interactions.  Specifically, he probed the molecular interplay between hydrophobic mismatch and transmembrane helix tilt and how proteins or peptides can modulate membrane curvature.

His postdoctoral research in the Griffin lab centered on magic-angle-spinning methods that permitted him to address an expanded array of biological and biophysical questions.  His work focused on both the methodological aspects of solid-state NMR and the applications to determine protein structure and dynamics, including the application of low-temperature dynamic nuclear polarization (DNP) to amyloid-related samples and on the effect of low temperatures on protein dynamics and solid-state NMR spectra.  Using various magic angle spinning methods, Dr. van der Wel characterized structure and in particular, the internal conformations, of amyloid fibrils.

At the University of Pittsburgh, his lab uses an array of solid-state NMR measurements of site-specific structure as well as dynamics to further our understanding of protein-membrane interactions and amyloid formation.  A particular focus has been on the aggregation process associated with polyglutamine expansion in Huntington’s disease and related disorders.  Dr. van der Wel has published more than 30 papers, covering topics ranging from amyloid formation and structure, to membrane biophysics, to low-temperature DNP, to magic angle spinning and oriented-membrane solid-state NMR spectroscopy.

The award, sponsored by Agilent Technologies, Inc., will be presented on Tuesday, November 19th from 2 to 5 pm.
