Dr. Anju Sreelatha received her B.S. in Biochemistry from the University of Texas at Dallas in 2009. Following a research fellowship with the UT Dallas Green Fellows Program, Dr. Sreelatha earned her Ph.D. from UT Southwestern in 2014 under the supervision of Kim Orth, Ph.D. During her graduate work, she identified the biochemical activity and molecular mechanism of a bacterial effector protein, VopQ. These studies provided a better understanding of bacterial pathogenesis and also offered new insight into the host cell mechanisms of autophagy and vesicle fusion. As a postdoctoral fellow with Vincent Tagliabracci, Ph.D. she discovered a new catalytic activity for the protein kinase fold and the selenoprotein family. Her postdoctoral work on Selenoprotein O revealed a new paradigm in cellular antioxidant pathways. In 2019, Anju joined the Department of Physiology as an Assistant Professor.
The Sreelatha lab is focused on studying the role of SelO in the mitochondria using mammalian systems. The lab utilizes a multidisciplinary approach with structural biology, biochemistry, molecular biology, and cell biology to unravel the molecular mechanisms of selenoproteins in health and disease.
