Synaptic adhesion molecules regulate diverse aspects of synapse formation and maintenance. Many known synaptic adhesion molecules localize at excitatory synapses, whereas relatively little is known about inhibitory synaptic adhesion molecules. Here we report that IgSF9b is a novel, brain-specific, homophilic adhesion molecule that is strongly expressed in GABAergic interneurons. IgSF9b was preferentially localized at inhibitory synapses in cultured rat hippocampal and cortical interneurons and was required for the development of inhibitory synapses onto interneurons. IgSF9b formed a subsynaptic domain distinct from the GABAA receptor– and gephyrin-containing domain, as indicated by super-resolution imaging. IgSF9b was linked to neuroligin 2, an inhibitory synaptic adhesion molecule coupled to gephyrin, via the multi-PDZ protein S-SCAM. IgSF9b and neuroligin 2 could reciprocally cluster each other. These results suggest a novel mode of inhibitory synaptic organization in which two subsynaptic domains, one containing IgSF9b for synaptic adhesion and the other containing gephyrin and GABAA receptors for synaptic transmission, are interconnected through S-SCAM and neuroligin 2. 相似文献

PTEN-induced putative kinase 1 (PINK1) and Parkin, encoded by their respective genes associated with Parkinson’s disease (PD), are linked in a common pathway involved in the protection of mitochondrial integrity and function. However, the mechanism of their interaction at the biochemical level has not been investigated yet. Using both mammalian and Drosophila systems, we here demonstrate that the PINK1 kinase activity is required for its function in mitochondria. PINK1 regulates the localization of Parkin to the mitochondria in its kinase activity-dependent manner. In detail, Parkin phosphorylation by PINK1 on its linker region promotes its mitochondrial translocation, and the RING1 domain of Parkin is critical for this occurrence. These results demonstrate the biochemical relationship between PINK1, Parkin, and the mitochondria and thereby suggest the possible mechanism of PINK-Parkin-associated PD pathogenesis. 相似文献
