Outline of Final Research Achievements

Recently, adhesion-type G protein-coupled receptors (ADGRs) have been intensively studied as molecules which regulate synapse integrity and learning & memory in the CNS. ADGR has a unique structure which contains an extracellular N-terminal domain with various types of functional domains, a seven-transmembrane region and an intracellular domain interacting with several signal molecules including G proteins. Despite its unique structure, the mechanisms by which ADGR behaves at synapses have remained unclear. In this study, we demonstrated that a brain-specific angiogenesis inhibitor 3 (BAI3), an ADGR member abundantly expressed at the synapses between climbing fiber (CF) and Purkinje cell in the cerebellum, plays crucial roles in synapse morphology, synaptic plasticity and cerebellar motor learning.
