Division of Biology presents Daniel Klionsky April 27
Submitted by Division of Biology
Daniel Klionsky, 1xbet online games login of Michigan, will present "If You Only Have Time to Attend One Seminar on Autophagy Today, This is the One" as part of the Division of Biology Seminar Series at 4 p.m. Friday, April 27, in 221 Ackert Hall.
The abstract for the lecture will coverMacro 1xbet online games login /1xbet online games login , a process of cellular self-digestion that plays a critical role in cytoprotective responses to stress. Defects in 1xbet online games login in humans are associated with a wide range of pathologies including cancer, neurodegeneration, diabetes, and heart disease. Designing effective therapies for these pathophysiologies will require a greater understanding of the mechanism and regulation of 1xbet online games login . The overall pathway and the protein components of 1xbet online games login are highly conserved from yeast to human; over forty 1xbet online games login -related (ATG) genes have been identified in yeast, and homologs exist for many of them in more complex eukaryotes. Many questions concerning the molecular basis of the 1xbet online games login pathway remain unanswered. For example, how is the initial sequestering compartment, the phagophore, nucleated? What is the origin of the membrane used for expansion of the phagophore to form the autophagosome? What are the roles of the various Atg proteins in the process of autophagosome biogenesis?
We have been analyzing the regulation of 1xbet online games login in Saccharomyces cerevisiae. Two of the central 1xbet online games login -related proteins are Atg8 and Atg9: The amount of Atg8 determines the size of autophagosomes, whereas the Atg9 level controls the rate of autophagosome formation; therefore, we are interested in the transcriptional and post-transcriptional processes that regulate their function. The ATG8 gene in particular is controlled through a complex network that involves negative regulation through several distinct mechanisms; this ensures an appropriate level of homeostatic 1xbet online games login , while preparing cells to rapidly induce 1xbet online games login when they encounter stress.
