Teasing out a role for tepsin in AP-4 mediated trafficking
May. 21, 2024—AP-4 is one complex in a family of coat proteins that mediate vesicle formation at various membranes. Previous work has determined that AP-4 is recruited specifically to the trans-Golgi network, but the exact mechanisms governing AP-4 vesicle budding or distribution are still poorly understood. Further, loss of the AP-4 complex in humans results in a...
Vanderbilt Phenocam goes live
May. 21, 2024—The Phenocam at Vanderbilt monitors changes in tree canopy greenness and updates at thirty-minute intervals.

The Vanderbilt site is part of the PhenoCam Network, a cooperative network of more than...
Vanderbilt launches sustainable lab program
May. 21, 2024—Did you know that laboratory spaces traditionally consume about five times more energy per square foot than standard office spaces? In an effort to help reduce the environmental impact of lab activities, Vanderbilt has launched the Vanderbilt Sustainable Labs program. VSL is an initiative from Environmental Health, Safety and Sustainability in the Division of Administration...
Iverson Lab provides new insights on chemotaxis
May. 3, 2024—The lab of Tina Iverson, Louise B. McGavock Professor and professor of pharmacology, in collaboration with researchers at the University of California, San Francisco; Stanford University; and The Weizmann Institute of Science in Israel have published new work in Nature Microbiology, providing new insights on chemotaxis. Chemotaxis is a key characteristic shared by all infectious...
Chazin to lead biomedical research education and training
Apr. 9, 2024—Congratulations to Walter Chazin, founder and former director of the Center of Structural Biology, on being named senior associate dean of BRET! Walter takes over from Kathleen Gould, who steps down after 14 years of leading the BRET Office to return her focus to her research program. Read the full announcement on the Basic Sciences...
Illuminating a critical step in DNA replication
Mar. 22, 2024—Brandt Eichman (Biological Sciences) and Walter Chazin (Biochemistry and Chemistry) recently visualized a multi-functional protein in action using the state-of-the-art CSB Cryo-EM Facility. The findings, recently published in Nature Structural & Molecular Biology, shed light on how DNA replication is initiated in humans. Read their reflections on this critical research in this Q&A with the...

The team—Melissa Chambers, Scott Collier, Mariam Haider—is available to assist users with CryoSPARC data processing, general EM data processing, sample prep, microscope operation, etc. If you can’t make it to the Engineering Science Building, email any staff member...
CSB Core Update
Feb. 21, 2024—The Biophysical Instrumentation Core and the Megalab Core have been combined to form the new Vanderbilt Center for Structural Biology Labs and Instrumentation Facility. The facility supports mass photometry, biolayer interferometry, stopped-flow spectrometry, microscale thermophoresis, dynamic light scattering, circular dichroism and microcalorimetry instruments for measuring macromolecular conformation, stability and binding interactions. The facility also provides...
Enzyme substrate positioning dynamics: To be electrostatic or not to be?
Feb. 9, 2024—Bioengineered enzymes are used in a wide variety of applications including chemical synthesis, waste degradation, fuel production, disease diagnosis and treatment. The development of efficient enzymes can be accelerated by understanding the catalytic origin of enzymes, a fundamental question in the field of chemistry. Catalysis is believed to rely largely on protein dynamics, one facet...
Ben Brown receives grant to develop nonaddictive painkillers with AI
Feb. 2, 2024—Ben Brown, assistant research professor in chemistry, was recently awarded $2.375M to develop nonaddictive painkillers with AI. The grant, an Avenir Award in Chemistry and Pharmacology of Substance Use Disorders, is awarded by NIDA to early-stage investigators who propose highly innovative studies and represent the future of addiction science. Ben’s research will focus on Mu-opioid...
John Yang appointed to JCTC Early Career Board
Feb. 2, 2024—John Yang, assistant professor of chemistry, was recently appointed to the inaugural Early Career Board (ECB) for the Journal of Chemical Theory and Computation (JCTC). The ECB initiative provides young investigators with guidance and insight into the editorial process as they pursue their independent research careers. The members will also provide input on journal strategies, act...
Eli McDonald presents Karpay Award Seminar January 23
Jan. 19, 2024—2024 Karpay Award Winner Eli McDonald, of the Meiler and Plate Labs, gives the MBTP/CSB Seminar on Tuesday, January 23, at 12:20pm in 1220 MRB3. Eli was drawn to scientific research from an early age. He studied the molecular dynamics of phospholipid bilayer self-assembly as an undergraduate at Vanderbilt University before joining Jens Meiler and...
Delving into polymerase α-primase dynamics
Jan. 5, 2024—In eukaryotes, DNA replication relies on the synthesis of a chimeric RNA/DNA primer by the heterotetrameric polymerase α-primase (pol-prim) enzyme. The primers generated by pol-prim consist of 7-10 ribonucleotides followed by ~20 deoxyribonucleotides and are generated by distinct active sites in the primase and polymerase subunits. Both primase and polymerase α consist of a catalytic...
A new toxin toolkit for C. diff
Dec. 1, 2023—Clostridioides difficile (C. diff) is a leading cause of diarrhea and healthcare-associated infections in the United States and recognized as an urgent threat by the Centers for Disease Control. Virulence of C. diff infections is believed to rely primarily on the production of two toxins: TcdA and TcdB. TcdA and TcdB are large homologous proteins...
