產(chǎn)品詳情

產(chǎn)品描述：

The NELFB antibody (CSB-PA03765A0Rb) is produced in the rabbit with a peptide corresponding to amino acids 8-199 of the human NELFB immunized. This polyclonal antibody occurs as an unconjugated IgG. Its purity is 95%+ using protein G purified. It is reactive with human and mouse samples. The NELFB protein is a subunit of NELF, which is known to enforce promoter-proximal pausing of RNA polymerase II. The functional cardiac deterioration in NELFB knockout mice strongly indicates an important role of NELFB in the maintenance of normal cardiac contractility under stressed conditions. This anti-NELFB antibody has been quality-verified in ELISA, WB, IHC, and ChIP applications.

靶點詳情

功能：

Essential component of the NELF complex, a complex that negatively regulates the elongation of transcription by RNA polymerase II. The NELF complex, which acts via an association with the DSIF complex and causes transcriptional pausing, is counteracted by the P-TEFb kinase complex. May be able to induce chromatin unfolding. Essential for early embryogenesis; plays an important role in maintaining the undifferentiated state of embryonic stem cells (ESCs) by preventing unscheduled expression of developmental genes. Plays a key role in establishing the responsiveness of stem cells to developmental cues; facilitates plasticity and cell fate commitment in ESCs by establishing the appropriate expression level of signaling molecules. Supports the transcription of genes involved in energy metabolism in cardiomyocytes; facilitates the association of transcription initiation factors with the promoters of the metabolism-related genes.; (Microbial infection) The NELF complex is involved in HIV-1 latency possibly involving recruitment of PCF11 to paused RNA polymerase II. In vitro, binds weakly to the HIV-1 TAR RNA which is located in the long terminal repeat (LTR) of HIV-1.

2. A positively charged face of NELF-AC is involved in RNA binding, whereas the opposite face of the NELF-AC subcomplex binds NELF-B. NELF-B is predicted to form a HEAT repeat fold, also binds RNA in vivo, and anchors the subunit NELF-E, which is confirmed to bind RNA in vivo. PMID: 27282391
3. High COBRA1 expression is associated with hepatocellular carcinoma. PMID: 28112367
4. both human and mouse NELF-B proteins are translated from a non-AUG codon upstream of the annotated AUG. PMID: 26010750
5. These studies allow us to position the actions of two new modulators of GR-regulated transactivation, NELF-A and NELF-B, relative to other factors in the overall gene induction sequence. PMID: 24097989
6. data show that NELF subunits exhibit highly specific subcellular localizations, such as in NELF bodies or in midbodies, and some shuttle actively between the nucleus and cytoplasm; loss of NELF from cells can lead to enlarged and/or multiple nuclei PMID: 19245807
7. NELF-C and NELF-D are highly related or identical to the protein called TH1, of unknown function. NELF-B and NELF-C or NELF-D are integral subunits that bring NELF-A and NELF-E together. [NELF-B] [NELF-C] PMID: 12612062
8. differentially expressed in breast cancer cell lines, antibody to it may be a useful tool to investigate its functions PMID: 15185750
9. COBRA1 may directly modulate AP-1 pathway and, therefore, may play important roles in cell proliferation, differentiation, apoptosis, and oncogenesis. PMID: 15530430
10. COBRA1 can negatively regulate the activator protein-1 (AP-1) complex at the TFF1 promoter and thus down-regulate TFF1 expression in gastric cancer cell lines. PMID: 16452188
11. Decreasing NELF also correlated with displacement of a positioned nucleosome and increased acetylation of histone H4, suggesting coupling of transcription elongation and chromatin remodeling PMID: 17442680
12. Negative elongation factor (NELF) is a four subunit transcription factor. Our results point to a surprising role of NELF in the 3' end processing of histone mRNAs and suggest that NELF is a new factor that coordinates mRNA processing in transcription. PMID: 17499042
13. COBRA1 may coordinate multiple steps in ligand-dependent gene expression, which in turn ensures both the quantity and quality of hormone-stimulated gene products PMID: 17659869
14. a lack of COBRA1 expression in breast carcinoma may serve as a useful indicator for poor prognosis. PMID: 17910036
15. COBRA1 and BRCA1 may engage in common gene regulatory pathways to suppress breast cancer progression. PMID: 18071589
