Axonal growth is fundamental to the establishment of neuronal connectivity in the brain. However, the cell-intrinsic mechanisms that govern axonal morphogenesis remain to be elucidated. The ubiquitin ligase Cdh1-anaphase-promoting complex (Cdh1-APC) suppresses the growth of axons in postmitotic neurons. Here, we report that Cdh1-APC operates in the nucleus(More)
The transcriptional corepressor SnoN is a critical regulator of axonal morphogenesis, but how SnoN drives axonal growth is unknown. Here, we report that gene-profiling analyses in cerebellar granule neurons reveal that the large majority of genes altered upon SnoN knockdown are surprisingly downregulated, suggesting that SnoN may activate transcription in(More)
Axon growth is critical to the establishment of neuronal connectivity. The E3 ubiquitin ligase Cdh1-anaphase-promoting complex (Cdh1-APC) and its substrate the transcriptional modulator SnoN form a cell-intrinsic pathway that orchestrates axonal morphogenesis in the mammalian brain. How the Cdh1-APC/SnoN pathway is controlled in the nervous system remained(More)
The ubiquitin ligase Cdh1-anaphase promoting complex (Cdh1-APC) plays a key role in the control of axonal morphogenesis in the mammalian brain, but the mechanisms that regulate neuronal Cdh1-APC function remain incompletely understood. Here, we have characterized the effect of phosphorylation of Cdh1 at cyclin-dependent kinase (Cdk) sites on Cdh1-APC(More)
Control of neuronal positioning is fundamental to normal brain development. However, the cell-intrinsic mechanisms that govern neuronal positioning remain to be elucidated. Here, we report that the spliced protein products of the transcriptional regulator SnoN, SnoN1 and SnoN2, harbor opposing functions in the coordinate regulation of neuronal branching and(More)
