- Biography
Dr. Angela “Angie” Mabb joined the faculty at Georgia State University in 2016 and is currently 2CI Assistant Professor at the Neuroscience Institute and Center for Behavioral Neurosciences. Angie received her undergraduate degree from Clarkson University dual majoring in Chemistry and Bio-Molecular Science. She then received her Ph.D. at the University of Wisconsin-Madison under the direction of Dr. Shigeki Miyamoto, where she focused on how posttranslational modifications contributed to pathways of chemoresistance in response to topoisomerase inhibitors.
Dr. Mabb’s switch to the field of neuroscience dovetailed well with her graduate work, as she utilized her biochemical acumen to explore pathways of synaptic transmission and receptor trafficking in the nervous system at Duke University under the direction of Dr. Michael D. Ehlers. Here, she investigated how a group of enzymes called E3 ubiquitin ligases mediate synaptic transmission and plasticity in the nervous system. Her findings allowed a solution to a long-standing problem in the field of neuroscience: How can one temporally tune synaptic plasticity/transmission during elevated bouts of synaptic drive? While at Duke, Dr. Mabb was a recipient of the Ruth K. Broad Fellowship and was awarded the National Service Research Award (NRSA) from the NIH/NINDS.
Dr. Mabb then migrated to the University of North Carolina-Chapel Hill under the direction of Dr. Benjamin D. Philpot and Dr. Mark J. Zylka. Here she focused on understanding pathways involved in brain-specific epigenetic regulation, with a particular focus on the epigenetically imprinted E3, UBE3A, a gene whose dysfunction has been linked to autism, Angelman syndrome, and cervical cancer. While at UNC, she was the recipient of the Joseph E. Wagstaff Postdoctoral Fellowship from the Angelman Syndrome Foundation.
At GSU, Dr. Mabb’s lab is focused on understanding how disruptions in ubiquitin pathways in the nervous system lead to a multitude of neurological disorders. Her approach is to utilize and develop molecular biology methods and tools to explore ubiquitin pathways involved in nervous system function and disease. In Dr. Mabb’s lab, students will gain experience or have exposure to the following: primary neuron culture preparations, standard biochemical techniques, proteomics, confocal microscopy, use of transgenic mouse models, in vivo imaging, electrophysiology, and animal behavior. Research in the Mabb lab is currently funded by the NIH and NSF.
