Distinct cis elements in the 3' UTR of the C. elegans cebp-1 mRNA mediate its regulation in neuronal development.

ABSTRACT: The 3' untranslated regions (3' UTRs) of mRNAs mediate post-transcriptional regulation of genes in many biological processes. Cis elements in 3' UTRs can interact with RNA-binding factors in sequence-specific or structure-dependent manners, enabling regulation of mRNA stability, translation, and localization. Caenorhabditis elegans CEBP-1 is a conserved transcription factor of the C/EBP family, and functions in diverse contexts, from neuronal development and axon regeneration to organismal growth. Previous studies revealed that the levels of cebp-1 mRNA in neurons depend on its 3' UTR and are also negatively regulated by the E3 ubiquitin ligase RPM-1. Here, by systematically dissecting cebp-1's 3' UTR, we test the roles of specific cis elements in cebp-1 expression and function in neurons.
