Biochem/physiol Actions

CUGBP2 is an RNA-binding protein that specifically binds to CUG repeat sequences and is responsible for the regulation of both nuclear and cytoplasmic RNA processing events such as alternative splicing, RNA editing, mRNA stability, and translation. It is mainly expressed in muscle and brain. It regulates a specific alternative slicing of exons 5 and 21 of the N-methyl-D-aspartate receptor 1 (NMDA R1) RNA in rat. It binds to U/G-rich motifs within muscle specific enhancer elements (MSEs) and activates inclusion of an alternative exon in cardiac troponin T (cTNT) pre-mRNAs. It interacts with A/U rich sequences in the 3′ UTR and inhibits translation of cycloxygenase-2 (COX-2) mRNAs.

Target description

CUGBP2 is an RNA-binding protein that specificallybinds to CUG repeat sequences.

Cell-type-specific and inducible alternative splicing has a fundamental impact on regulating gene expression and cellular function in a variety of settings, including activation and differentiation. We have recently shown that activation-induced skipping of TRAF3 exon 8 activates noncanonical NF-κB signaling...

Alternative RNA splicing generates extensive proteomic diversity in the nervous system, yet few neural-specific RNA binding proteins have been implicated in splicing control. Here we show that the biochemical properties and spatial expression of mouse neuroblastoma apoptosis-related RNA-binding protein (NAPOR;...

Cyclooxygenase-2 (COX-2) expression is translationally silenced in epithelial cells undergoing radiation-induced apoptosis. CUGBP2, a predominantly nuclear protein, is also rapidly induced in response to radiation and translocates to the cytoplasm. Antisense-mediated suppression of CUGBP2 renders radioprotection through a COX-2-dependent prostaglandin...

Embryonic lethal abnormal vision (ELAV) type RNA binding protein 3 (ETR-3; also called NAPOR, CUGBP2, or BRUNOL3) has been implicated in the regulation of nuclear and cytoplasmic RNA processing events, including alternative splicing, RNA editing, stability and translation. Here, we...

Alternative splicing of cardiac troponin T (cTNT) exon 5 undergoes a developmentally regulated switch such that exon inclusion predominates in embryonic, but not adult, striated muscle. We previously described four muscle-specific splicing enhancers (MSEs) within introns flanking exon 5 in...
