Apparently,the genomes of many organisms are pervasively transcribed,and long noncoding RNAs(lncRNAs)make up the majority of cellular transcripts.LncRNAs have been reported to play important roles in many biological processes;however,their effects on locomotion are poorly understood.Here,we presented a novel lncRNA,Loco-motion Regulatory Gene(LRG),which participates in locomotion by sequestering Synap-totagmin 1(SYT1).LRG deficiency resulted in higher locomotion speed which could be rescued by pan-neuronal overexpression but not by limited ellipsoid body,motoneuron or muscle-expression of LRG.At the molecular level,the synaptic vesicles(SVs)release and movement-related SYT1 protein was recognized as LRG-interacting protein candidate.Furthermore,LRG had no effects on SYT1 expression.Genetically,the behavioral defects in LRG mutant could be rescued by pan-neuronal knock-down of Syt1.Taken together,all the results suggested LRG exerts regulatory effects on locomotion via sequestering SYT1 thereby blocking its function without affecting its expression.Our work displays a new function of lncRNA and provides insights for revealing the pathogenesis of neurological diseases with motor disorders.
