Novel intestinal splice variants of RNA-binding protein CUGBP2: isoform-specific effects on mitotic catastrophe.
CUG triplet repeat-binding protein 2 (CUGBP2) is a RNA-binding protein that regulates mRNA translation and modulates apoptosis. Here, we report the identification of two splice variants (termed variants 2 and 3) in cultured human intestinal epithelial cells and in mouse gastrointestinal tract. The variants are generated from alternative upstream promoters resulting in the inclusion of additiona...
متن کاملTranslation inhibition during cell cycle arrest and apoptosis: Mcl-1 is a novel target for RNA binding protein CUGBP2.
CUGBP2, a translation inhibitor, induces colon cancer cells to undergo apoptosis. Mcl-1, an antiapoptotic Bcl-2 family protein, interferes with mitochondrial activation to inhibit apoptosis. Here, we have determined the effect of CUGBP2 on Mcl-1 expression. We developed a HCUG2 cell line by stably expressing CUGBP2 in the HCT-116 colon cancer cells. HCUG2 cells demonstrate decreased levels of p...
متن کاملRNA-guided genome editing of mammalian cells.
The microbial CRISPR-Cas adaptive immune system can be harnessed to facilitate genome editing in eukaryotic cells (Cong L et al., Science 339, 819-823, 2013; Mali P et al., Science 339, 823-826, 2013). Here we describe a protocol for the use of the RNA-guided Cas9 nuclease from the Streptococcus pyogenes type II CRISPR system to achieve specific, scalable, and cost-efficient genome editing in m...
متن کاملAssociation of guide RNA binding protein gBP21 with active RNA editing complexes in Trypanosoma brucei.
RNA editing in Trypanosoma brucei mitochondria produces mature mRNAs by a series of enzyme-catalyzed reactions that specifically insert or delete uridylates in association with a macromolecular complex. Using a mitochondrial fraction enriched for in vitro RNA editing activity, we produced several monoclonal antibodies that are specific for a 21-kDa guide RNA (gRNA) binding protein initially ide...
متن کاملRNA Editing RNA
RNA Editing RNA editing is a term used to describe a diverse set of phenomena in which mRNA, rRNA, and tRNA transcripts are modified in sequence after transcription. The types of RNA editing vary from uridine (U) or cytidine (C) insertions and deletions within coding regions of mitochondrial mRNAs to the substitution of specific C residues with U residues in plant mitochondrial mRNAs or the sub...
