microRNAs (miRNAs) are small ( approximately 22 nt) noncoding RNAs that have been shown to regulate gene expression post-transcriptionally. They function by pairing with the 3' UTR of target mRNAs and repressing translation or by targeting the mRNA for degradation. miRNAs are involved in diverse aspects of development, maintenance, and disease, and are(More)
SNAP-25 is a core component of the trimeric SNARE complex mediating vesicle exocytosis during membrane addition for neuronal growth, neuropeptide/growth factor secretion, and neurotransmitter release during synaptic transmission. Here, we report a novel microRNA mechanism of SNAP-25 regulation controlling motor neuron development, neurosecretion, synaptic(More)
microRNAs (miRNAs) are a family of 21-23 nucleotide endogenous non-coding RNAs that post-transcriptionally regulate gene expression in a sequence-specific manner. Typically, miRNAs downregulate target genes by recognizing and recruiting protein complexes to 3'UTRs, followed by translation repression or mRNA degradation. miR-92 is a well-studied oncogene in(More)
Precise regulation of Notch signaling is essential for normal vertebrate development. Mind bomb (Mib) is a ubiquitin ligase that is required for activation of Notch by Notch׳s ligand, Delta. Sorting Nexin 5 (SNX5) co-localizes with Mib and Delta complexes and has been shown to directly bind to Mib. We show that microRNA-216a (miR-216a) is expressed in the(More)
