These proteins function as molecular machines and switches that can fail to work properly for various reasons, causing diseases such as cancer. We employ biochemical, biophysical, and structural biology techniques, in particular small angle neutron and x-ray scattering (SAXS and SANS), to study the interactions of these proteins. We also develop methods of utilizing quasielastic neutron scattering, in particular neutron spin echo spectroscopy (NSE) to study protein dynamics and protein domain motions. We have developed a theoretical framework using non-equilibrium statistical mechanics to interpret the NSE data. These methods allow us to see, for the first time, the dynamics of protein complexes on nanometer scales. NSE fills an important information gap in our ability to study protein motion on sub-microsecond time scales and on nanometer length scales.

Lluı´s Companys 23, 08010 Barcelona, Spain *Correspondence: [email protected] http://dx.doi.org/10.1016/j.str.2012.10.002 In recent years, high-throughput discovery of macromolecular protein structures and complexes has played a major role in advancing a more systems-oriented view of protein interaction and signaling networks. The design of biological systems often employs structural information or structure-based protein design to successfully implement synthetic signaling circuits or for rewiring signaling flows. Here, we summarize the latest advances in using structural information for studying protein interaction and signaling networks, and in synthetic biology approaches. We then provide a perspective of how combining structural biology with engineered cell signaling modules—using additional information from quantitative biochemistry and proteo- mics, gene evolution, and mathematical modeling—can provide insight into signaling modules and the general design principles of cell signaling. Ultimately, this will improve our understanding of cell- and tissue-type-specific signal transduction. Integrating the quantitative effects of disease mutations into these systems may provide a basis for elucidating the molecular mechanisms of diseases.

  • MOLECULAR BIOPHYSICS and BIOCHEMISTRY* by William C. Summers
    MOLECULAR BIOPHYSICS AND BIOCHEMISTRY* by William C. Summers (Professor of Therapeutic Radiology, Molecular Biophysics and Biochemistry, and History of Medicine, and Lecturer in History) MOLECULAR BIOPHYSICS During World War II many university physicists undertook new research programs aimed at wartime goals. Notable among these goals were the Manhattan Project to investigate and exploit nuclear energy for military purposes and the project, based at the MIT Radiation Laboratory, to develop radar as a military surveillance tool. Yale nuclear physicist Ernest Pollard, a student of Chadwick and Rutherford, was recruited for the Radiation Lab (known informally as the “Rad Lab”) by Ernest Lawrence. Prior to the war, Pollard had been carrying on a modest program of teaching and research in nuclear physics at Yale in the Department of Physics, then chaired by William Watson. In Pollard’s view, wartime physics research fundamentally changed the style and form of physics in America. Nuclear physics had become big science, requiring expensive equipment and teams of scientists, not an activity for a university professor with a small research group and major teaching obligations. In addition, having spent the war years working on microwave research, Pollard and other members of the Rad Lab had lost out on the excitement and new advances, many of them still classified, in nuclear physics coming out of the Manhattan Project. When Pollard and his small group of students, including Franklin Hutchinson, returned to Yale after the war, he considered two new directions for his research, cosmology and biology. In Pollard’s view, he was not temperamentally suited to be a cosmologist, and he thought it might be hard to start up in that field at Yale at that time.

  • Quantum Mechanics Atomic, Molecular, and Optical Physics
    Quantum Mechanics_Atomic, molecular, and optical physics Atomic, molecular, and optical physics (AMO) is the study of matter-matter and light- matter interactions; at the scale of one or a few atoms [1] and energy scales around several electron volts[2]:1356.[3] The three areas are closely interrelated. AMO theory includes classical,semi-classical and quantum treatments. Typically, the theory and applications of emission, absorption,scattering of electromagnetic radiation (light) fromexcited atoms and molecules, analysis of spectroscopy, generation of lasers and masers, and the optical properties of matter in general, fall into these categories. Atomic and molecular physics Atomic physics is the subfield of AMO that studies atoms as an isolated system of electrons and an atomic nucleus, while Molecular physics is the study of the physical properties of molecules. The term atomic physics is often associated withnuclear power and nuclear bombs, due to the synonymous use of atomic andnuclear in standard English. However, physicists distinguish between atomic physics — which deals with the atom as a system consisting of a nucleus and electrons — and nuclear physics, which considers atomic nuclei alone. The important experimental techniques are the various types of spectroscopy. Molecular physics, while closely related to Atomic physics, also overlaps greatly with theoretical chemistry, physical chemistry and chemical physics.[4] Both subfields are primarily concerned with electronic structure and the dynamical processes by which these arrangements change. Generally this work involves using quantum mechanics. For molecular physics this approach is known as Quantum chemistry. One important aspect of molecular physics is that the essential atomic orbital theory in the field of atomic physics expands to themolecular orbital theory.[5] Molecular physics is concerned with atomic processes in molecules, but it is additionally concerned with effects due to the molecular structure.

  • Suggested Guidelines for Starting an Undergraduate Biophysics Program
    Suggested Guidelines for Starting an Undergraduate Biophysics Program A biophysics major explores the bridge between biology and physics, applying quantitative methods to solve problems in biology, medicine, and related fields. A biophysics program is interdisciplinary, drawing from coursework in physics, biology, chemistry, mathematics, and statistics. It combines a broad science curriculum with physical and mathematical rigor in prepa- ration for diverse careers. The need for STEM education is well documented. Studies including the influential 2007 National Academies report “Rising Above the Gathering Storm: Energizing and Employing America for a Brighter Economic Future” have warned of potential weaknesses existing in the U.S. STEM education system, and how addressing it relates to national prosperity and power [1]. In the succeeding decade, positive efforts have been made over the entire educational spectrum. Still, there may be a need for over one million more college graduates in STEM fields above the current trajectory in the coming decade [2]. Documented trends indicate the need for interdisciplinary STEM options in particular. For example, the U.S. Department of Labor, Bureau of Labor Statistics projects, from 2014-2024, an increase in employment among interdisciplinary fields like bio- medical engineering (23%), environmental science (11%), and biochemistry/biophysics (8%), above the projected increase for fields like microbiology (4%), physics (7%), and chemistry (3%) [3]. As an interdisciplinary STEM option, a biophysics program brings together faculty from across disciplines, encouraging inter- actions, and potentially leading research and funding opportunities. Further, an undergraduate biophysics program may have a relatively easy implementation, as much of the core coursework (physics, chemistry, biology, and mathematics) is already offered at most institutions.
