Nxnl2 splicing results in dual functions in neuronal cell survival and maintenance of cell integrity.
The rod-derived cone viability factors, RdCVF and RdCVF2, have potential therapeutical interests for the treatment of inherited photoreceptor degenerations. In the mouse lacking Nxnl2, the gene encoding RdCVF2, the progressive decline of the visual performance of the cones in parallel with their degeneration, arises due to the loss of trophic support from RdCVF2. In contrary, the progressive lo...
متن کاملProtein-RNA and protein-protein recognition by dual KH1/2 domains of the neuronal splicing factor Nova-1.
Nova onconeural antigens are neuron-specific RNA-binding proteins implicated in paraneoplastic opsoclonus-myoclonus-ataxia (POMA) syndrome. Nova harbors three K-homology (KH) motifs implicated in alternate splicing regulation of genes involved in inhibitory synaptic transmission. We report the crystal structure of the first two KH domains (KH1/2) of Nova-1 bound to an in vitro selected RNA hair...
متن کاملNOVA regulates Dcc alternative splicing during neuronal migration and axon guidance in the spinal cord
RNA-binding proteins (RBPs) control multiple aspects of post-transcriptional gene regulation and function during various biological processes in the nervous system. To further reveal the functional significance of RBPs during neural development, we carried out an in vivo RNAi screen in the dorsal spinal cord interneurons, including the commissural neurons. We found that the NOVA family of RBPs ...
متن کاملThe Neuronal Splicing Factor Nova Co-Localizes with Target RNAs in the Dendrite
Nova proteins are neuron-specific RNA binding proteins targeted by autoantibodies in a disorder manifest by failure of motor inhibition, and they regulate splicing and alternative 3' processing. Nova regulates splicing of RNAs encoding synaptic proteins, including the inhibitory glycine receptor alpha2 subunit (GlyRalpha2), and binds to others, including the GIRK2 channel. We found that Nova ha...
متن کاملNova-1 Regulates Neuron-Specific Alternative Splicing and Is Essential for Neuronal Viability
We have combined genetic and biochemical approaches to analyze the function of the RNA-binding protein Nova-1, the paraneoplastic opsoclonus-myoclonus ataxia (POMA) antigen. Nova-1 null mice die postnatally from a motor deficit associated with apoptotic death of spinal and brainstem neurons. Nova-1 null mice show specific splicing defects in two inhibitory receptor pre-mRNAs, glycine alpha2 exo...
