Jeff S Abramson is a Professor of Physiology in the David Geffen School of Medicine at the University of California Los Angeles (UCLA). His research focuses on the structural and functional characterization of membrane transport proteins, particularly sugar transporters and mitochondrial channels. He maintains an active laboratory investigating the molecular mechanisms of cellular transport processes. Dr. Abramson's primary research interests center on membrane transport proteins, with particular emphasis on sugar symporters and voltage-dependent anion channels (VDACs). His work combines structural biology, biophysics, and biochemistry to understand the molecular mechanisms of transport, including conformational changes during transport cycles, substrate recognition, and regulation by membrane potential. His research has significant implications for understanding metabolic disorders, mitochondrial function, and potential therapeutic targets. Analysis of Dr. Abramson's publication record reveals a consistent focus on membrane protein structure-function relationships over the past two decades. His work demonstrates expertise in X-ray crystallography, cryo-electron microscopy, and functional assays to characterize transport proteins. Recent publications show increasing emphasis on mitochondrial biology, particularly VDAC structure and function, while maintaining his longstanding interest in sugar transport mechanisms. His research bridges fundamental biophysical principles with potential biomedical applications in metabolic diseases. Dr. Abramson has been awarded multiple NIH grants supporting his research, including the R35GM135175 grant titled 'Deciphering molecular details of cellular sugar transport and their roles in disease' (2020-2024), R01GM124783 'Functional and structural studies of unique pathogenic transporters involved in glycobiology' (2017-2021), and R01GM078844 'Structural and functional characterization of sugar transporters in health and disease' (2006-2020). As Principal Investigator, Dr. Abramson has mentored numerous graduate students and postdoctoral researchers. His laboratory has made significant contributions to understanding the structure-function relationships of membrane transport proteins through collaborations with researchers across multiple disciplines. The lab utilizes advanced techniques including X-ray crystallography, cryo-EM, electrophysiology, and computational modeling to address fundamental questions about membrane protein mechanisms. Dr. Abramson's laboratory is part of UCLA's broader research ecosystem focused on structural biology and membrane protein research. His work intersects with several research centers at UCLA including those focused on metabolic diseases and structural biology. The lab maintains active collaborations with researchers specializing in biophysics, computational modeling, and disease mechanisms to translate basic findings into potential biomedical applications.
