PhD student<\/strong><\/p>\n

\"\"<\/div>\n

Research focus: <\/strong>Understanding enzyme dynamics is critical for elucidating the key features of enzyme structure and function. By using spectroscopic tools tied to transient-state kinetics methods, I seek to understand how real-time structural changes in the human enzymes IDH1, a metabolic enzyme, and PolE, a leading strand polymerase, facilitate their vital enzymatic activities.<\/p>\n

Brittany Conley<\/strong><\/a><\/h2>\n

PhD student<\/strong><\/p>\n

\"\"<\/p>\n

Research focus: <\/strong>Polymerase \u03b5 (PolE) is responsible for leading DNA strand replication in humans. Mutations in PolE drive cancers of the endometrium, stomach, and skin. These mutations can theoretically affect nucleotide incorporation, nucleotide excision, processivity, and overall fidelity. We use pre-steady-state kinetics experiments to determine the consequences of these mutations on robust, accurate DNA replication. I am interested in kinetically characterizing both exonuclease domain and polymerase domain mutants that drive tumors to elucidate the molecular mechanisms of tumor growth and development.<\/p>\n

Grace Chao<\/strong><\/h2>\n

PhD student (Biology)<\/strong><\/p>\n

\"\"<\/div>\n

Research focus: <\/strong>The conversion from isocitrate to \u03b1-ketoglutarate by IDH1 is the main source of NADPH in peroxisomes. Mutations in IDH1 prevent this conversion and can affect plasmalogen biosynthesis, \u03b2-oxidation of very long chain fatty acids, and \u03b1-oxidation of phytanic acid. I aim to use lipidomics and cellular assays to establish the peroxisomal consequences of IDH1 mutations that drive cancer.<\/p>\n

PhD student<\/strong><\/p>\n

\"\"<\/div>\n

Research focus: <\/strong>Human isocitrate dehydrogenase 2 (IDH2) is a mitochondrial metabolic enzyme that is commonly mutated in acute myeloid leukemia. Due to difficulties in heterologously expressing this protein, our understanding of its kinetic and structural features, both wild type and mutant forms, is limited. I seek to establish the key catalytic residues required for its conventional and neomorphic activities, and determine the static and dynamic structural features that support its function in health and disease.<\/p>\n

\"\"<\/div>\n

Research focus:<\/strong> Though isocitrate dehydrogenase 1 (IDH1) catalysis has been extensively studied in bacteria, the chemical details in humans, which have unique regulatory strategies from microbes, are less understood. I use site-directed mutagenesis to design mutants that will help us probe wild type IDH1 catalysis.<\/p>\n

\"\"<\/div>\n

Research focus: <\/strong>Mutant IDH is an important anti-cancer therapeutic target, and establishing selectivity features is critical for developing inhibitors that are efficacious and less toxic. I am interested in using biochemical techniques to understand inhibitor binding selectivity to mutant IDH1 and kinetic differences among tumor-driving mutants in IDH2.<\/p>\n

Sean Alfaro-Cunningham<\/strong><\/a><\/h2>\n

Biochemistry major, CREATE Scholar, LSAMP Scholar<\/strong><\/p>\n

Research focus:<\/strong> Mutations in isocitrate dehydrogenase (IDH) lead to the generation of a neomorphic activity, the production of D-2-hydroxyglutarate (D2HG). D2HG can serve as a competitive inhibitor of enzymes that use a structurally similar metabolite, \u03b1-ketoglutarate, that can ultimately lead to tumor formation. I am interested in identifying new pathways that may be affected by D2HG production by examining the consequences of treating \u03b1-ketoglutarate-dependent enzymes with D2HG.<\/p>\n

Josselyn Jacobo<\/b><\/h2>\n

Biology and Psychology double major, MARC Scholar<\/strong><\/p>\n

Research focus:<\/strong> A fundamental regulatory feature of human isocitrate dehydrogenase 1 (IDH1) is a mobile subdomain made up of the alpha-1o helix. The structural characteristics of this regulatory domain appear to depend on whether IDH1 has its substrate bound or is in its cofactor-bound-only form. However, this substrate dependency is not observed in IDH2; instead, this domain remains as a helical structure regardless of the absence or presence of substrates. I use site-directed mutagenesis and steady-state kinetic analysis to determine the structural features that drive the differences in this domain in IDH1 and IDH2.<\/p>\n
