Fig. 6. A schematic diagram of the mechanism of the Synage lncRNA in the regulation of synaptic and neuronal function in the WT and Synage KO mouse cerebella.
Synage lncRNA regulates stability and function of cerebellar synapses via at least two mechanisms. One is through the function of Synage as a sponge for mmu-miR-325-3p to regulate Cbln1 mRNA expression, which leads to the change of the CBLN1 protein levels. The other function is to serve as a scaffold for orchestrating the assembly of synaptic LRP1-HSP90AA1-PSD-95 complex.
