Theses and Dissertations (ETD)

Mammalian UNC-51–like kinases 1 and 2 (ULK1 and ULK2), Caenorhabditis elegans UNC-51 and Drosophila melanogaster Atg1 are redundant serine/threonine kinases that regulate flux through the autophagy pathway in response to various types of cellular stress. C. elegans UNC-51 and D. melanogaster Atg1 also promote axonal growth and defasciculation, and disruption of these genes results in defects in axon guidance in invertebrates. Germline Ulk1/2-deficient mice die perinatally. Therefore, we used a conditional-knockout approach to investigate the roles of ULK1/2 in the brain. Mice lacking Ulk1 and Ulk2 in their central nervous systems (CNS) showed defects in axonal pathfinding and defasciculation affecting …
