About the Chair

Joseph D. Etlinger, Ph.D.
Chair and Professor
Department of Cell Biology and Anatomy

With Alfred L. Goldberg, I discovered non-lysosomal ATP-dependent proteolytic activity, credited by awardees of the 2004 Nobel prize in chemistry, as the seminal observation revealing the proteasome/ubiquitin system. In subsequent studies, with my students and colleagues, we identified novel factors involved in the regulation of this pathway including a ubiquitin ligase critical to pulmonary arterial hypertension. We proposed how myofibrils turnover during muscle growth and atrophy and the roles of calcium, ATP, and beta -adrenergic receptors in these conditions. Finally, we have identified modalities to improve recovery from spinal cord injury including beta agonists, x-irradiation, and inhibitors of glucose toxicity.
