| Description | RIPAb+™ CUGBP2 - RIP Validated Antibody and Primer Set |
| Overview | RIPAb+ antibodies are evaluated using the RNA Binding Protein Immunoprecipitation (RIP) assay. Each RIPAb+ antibody set includes a negative control antibody to ensure specificity of the RIP reaction and is verified for the co-immunoprecipitation of RNA associated specifically with the immunoprecipitated RNA binding protein of interest. Where appropriate, the RIPAb+ set also includes quantitative RT-PCR control primers (RIP Primers) to biologically validate your IP results by successfully co-precipitating the specific RNA targets, such as messenger RNAs. The qPCR protocol and primer sequences are provided, allowing researchers to validate RIP protocols when using the antibody in their experimental context. If a target specific assay is not provided, the RIPAb+ kit is validated using an automated microfluidics-based assay by enrichment of detectable RNA over control immunoprecipitation. CUGBP2 is a RNA-binding protein implicated in the regulation of several post-transcriptional events including pre-mRNA alternative splicing, mRNA translation and stability. CUGBP2 mediates exon inclusion and/or exclusion in pre-mRNA that are subject to tissue-specific and developmentally regulated alternative splicing. |
| Background Information | The survival of motor neurons (SMN) complex is essential for the biogenesis of small nuclear ribonucleoprotein (snRNP) complexes in eukaryotic cells. Reduced levels of SMN cause the motor neuron degenerative disease, spinal muscular atrophy. Complexes containing Gemin3-Gemin4-Gemin5 and Gemin6-Gemin7-unrip persist at similar levels when SMN is reduced. Gemin5-containing subunits bind small nuclear RNA independently of the SMN complex and without a requirement for exogenous ATP. ATP hydrolysis is, however, required for displacement of small nuclear RNAs from the Gemin5-containing subunits and their assembly into snRNPs. |

| Application Notes | Immunoprecipitation from RIP lysate: Representative lot data. RIP lysate from Jurkat cells (~5 X 10E7 cell equivalents per IP) was subjected to immunoprecipitation using 5 µg of either a normal mouse IgG, (Cat. #CS200621), or 5 µg of Anti-CUGBP2 antibody (Cat. # CS204360). Precipitated proteins (lane 1: mouse IgG, lane 2: anti-CUGBP2) were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-CUGBP2 antibody (Cat. # CS204360, 1:1000). Proteins were visualized using One-Step™ IP-Western kit (GenScript Cat. # L00231) Arrow indicates CUGBP2 (Figure 2). Western Blot Analysis: Representative lot data. Lysates from HL60 cells were probed with a previous lot of Anti-CUGBP2 (1:1000 dilution). Arrow indicates CUGBP2 ~56 kDa (Figure 3). |

| Entrez Gene Number |
|
| Entrez Gene Summary | Members of the CELF/BRUNOL protein family contain two N-terminal RNA recognition motif (RRM) domains, one C-terminal RRM domain, and a divergent segment of 160-230 aa between the second and third RRM domains. Members of this protein family regulate pre-mRNA alternative splicing and may also be involved in mRNA editing, and translation. Alternative splicing results in multiple transcript variants encoding different isoforms. |

| UniProt Summary | FUNCTION: SwissProt: O95319 # RNA-binding protein implicated in the regulation of several post-transcriptional events. Involved in pre-mRNA alternative splicing, mRNA translation and stability. Mediates exon inclusion and/or exclusion in pre-mRNA that are subject to tissue-specific and developmentally regulated alternative splicing. Specifically activates exon 5 inclusion of TNNT2 in embryonic, but not adult, skeletal muscle. Activates TNNT2 exon 5 inclusion by antagonizing the repressive effect of PTB. Acts as both an activator and repressor of a pair of coregulated exons: promotes inclusion of the smooth muscle (SM) exon but exclusion of the non-muscle (NM) exon in actinin pre-mRNAs. Promotes inclusion of exonS 21 and exclusion of exon 5 of the NMDA receptor R1 pre- mRNA. Involved in the apoB RNA editing activity. Increases COX2 mRNA stability and inhibits COX2 mRNA translation in epithelial cells after radiation injury (By similarity). Modulates the cellular apoptosis program by regulating COX2-mediated prostaglandin E2 (PGE2) expression (By similarity). Binds to (CUG)n triplet repeats in the 3-UTR of transcripts such as DMPK. Binds to the muscle-specific splicing enhancer (MSE) intronic sites flanking the TNNT2 alternative exon 5. Binds preferentially to UG-rich sequences, in particular UG repeat and UGUU motifs. Binds to apoB mRNA, specifically to AU-rich sequences located immediatly upstream of the edited cytidine. Binds AU-rich sequences in the 3-UTR of COX2 mRNA (By similarity). Binds to an intronic RNA element responsible for the silencing of exon 21 splicing (By similarity). Binds to (CUG)n repeats (By similarity). SIZE: 508 amino acids; 54285 Da SUBUNIT: Found in a complex with APOBEC1 and ACF. SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Accumulates in the cytoplasm after ionizing radiation (By similarity). Colocalizes with APOBEC1 and ACF. RNA-binding activity is detected in both nuclear and cytoplasmic compartments. TISSUE SPECIFICITY: Expressed in frontal cortex. Isoform 1 is expressed in brain and lung. Isoform 2 is expressed in heart, brain, placenta, lung, liver, kidney, skeletal muscle and pancreas. Isoform 4 is expressed in heart, lung, skeletal muscle, kidney and pancreas. DEVELOPMENTAL STAGE: Isoform 1 is expressed in fetal brain.
