The cell adhesion molecule Dystroglycan has been shown to be involved in neural migration and axon targeting in multiple brain regions. In the hippocampus, Dystroglycan is involved in CCK+ basket axon targeting of pyramidal cells in CA1-3. In this dissertation, I show that Dystroglycan is also required for the function of these CCK+ basket synapses in a manner dependent on both the extracellular glycosylation of Dystroglycan and intracellular interactions with Dystroglycan. Similarly, I show that Dystroglycan is also located at cerebellar molecular layer interneuron synapses onto Purkinje cells and is required for the function of these synapses in a mechanism that mirrors that in the hippocampus. Finally, I identify Cntnap1 as a novel interacting partner of Dystroglycan in the brain. 000042751 540__ $$fCC BY 000042751 542__ $$fIn copyright - single owner 000042751 650__ $$aInterneurons$$020936 000042751 650__ $$aSynapses$$026704 000042751 650__ $$aPurkinje Cells$$024938 000042751 650__ $$aDystroglycans$$036156 000042751 6531_ $$aCntnap1 000042751 691__ $$aSchool of Medicine$$041369 000042751 692__ $$aVollum Institute$$041509 000042751 7001_ $$aJahncke, Jennifer$$uOregon Health and Science University$$041354$$10000-0003-2319-6109 000042751 8564_ $$93c726649-d8b2-41e2-b81e-031acf09c657$$s22799728$$uhttps://digitalcollections.ohsu.edu/record/42751/files/Jahncke.Jennifer.2024.pdf 000042751 909CO $$ooai:digitalcollections.ohsu.edu:42751$$pstudent-work 000042751 980__ $$aTheses and Dissertations 000042751 981__ $$aPublished$$b2024-03-18
