Biography

Daniel J. Finley is a Professor in the Department of Cell Biology at Harvard Medical School. His research is focused on the ubiquitin-proteasome pathway, exploring the mechanisms by which proteins are marked for degradation and the molecular functions of deubiquitinating enzymes. Ongoing projects include studying the deubiquitinating enzyme Usp14 and its yeast homolog Ubp6, both of which play critical roles in regulating the proteasome's ability to degrade ubiquitinated substrates. His work has revealed that Ubp6 non-catalytically inhibits the degradation of substrate proteins, while Usp14 enhances proteasome activity significantly. Finley and his colleagues are investigating the dynamic interactions between ubiquitin receptors and proteasomes, as well as the broader implications of ubiquitin-mediated degradation in cellular processes, particularly during the differentiation of erythroid cells. His research contributes to a deeper understanding of how selective degradation regulates protein homeostasis during critical developmental stages.
