NELFB is a subunit of negative elongation factor (NELF), which also includes NELFA (WHSC2\; MIM 606026), either NELFC or NELFD (TH1L\; MIM 605297), and NELFE (RDBP\; MIM 154040). Additionally we are shipping COBRA1 Proteins (9) and many more products for this protein.

High COBRA1 expression is associated with hepatocellular carcinoma.
both human and mouse NELF-B proteins are translated from a non-AUG codon upstream of the annotated AUG.
These studies allow us to position the actions of two new modulators of GR-regulated transactivation, NELF-A (show WHSC2 Antibodies) and NELF-B, relative to other factors in the overall gene induction sequence.
data show that NELF (show NELF Antibodies) subunits exhibit highly specific subcellular localizations, such as in NELF (show NELF Antibodies) bodies or in midbodies, and some shuttle actively between the nucleus and cytoplasm; loss of NELF (show NELF Antibodies) from cells can lead to enlarged and/or multiple nuclei
NELF-C (show TH1L Antibodies) and NELF-D (show TH1L Antibodies) are highly related or identical to the protein called TH1 (show TH1L Antibodies), of unknown function. NELF-B and NELF-C (show TH1L Antibodies) or NELF-D (show TH1L Antibodies) are integral subunits that bring NELF-A (show WHSC2 Antibodies) and NELF-E (show RDBP Antibodies) together. [NELF-B] [NELF-C (show TH1L Antibodies)]
COBRA1 may directly modulate AP-1 (show FOSB Antibodies) pathway and, therefore, may play important roles in cell proliferation, differentiation, apoptosis, and oncogenesis.
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.
Decreasing NELF also correlated with displacement of a positioned nucleosome and increased acetylation of histone H4, suggesting coupling of transcription elongation and chromatin remodeling
Negative elongation factor (NELF (show RDBP Antibodies)) is a four subunit transcription factor. Our results point to a surprising role of NELF (show NELF Antibodies) in the 3' end processing of histone mRNAs and suggest that NELF (show NELF Antibodies) is a new factor that coordinates mRNA processing in transcription.
COBRA1 may coordinate multiple steps in ligand-dependent gene expression, which in turn ensures both the quantity and quality of hormone-stimulated gene products
This study uncovers a previously unappreciated, DNA repair-independent function of BRCA1 (show BRCA1 Antibodies) in antagonizing COBRA1-dependent transcription program during mammary gland development.
Human and mouse Nelfb encode proteins translated from a non-AUG (CUG) start codon. The majority of mouse tissues examined express the isoform translated from the CUG start codon, but a small number of tissues also express a shorter isoform of the same apparent size as the AUG-initiated isoform.
Cobra1 Is Required for TrkC (show NTRK3 Antibodies)-Induced Apoptosis.
genetic and genomic studies provide new physiological and molecular insight into Nelf-mediated pol II pausing.
findings also indicate that Cobra1 helps maintain the undifferentiated state of mESCs by preventing unscheduled expression of developmental genes
NELFB is a subunit of negative elongation factor (NELF), which also includes NELFA (WHSC2\; MIM 606026), either NELFC or NELFD (TH1L\; MIM 605297), and NELFE (RDBP\; MIM 154040). NELF acts with DRB sensitivity-inducing factor (DSIF), a heterodimer of SPT4 (SUPT4H1\; MIM 603555) and SPT5 (SUPT5H\; MIM 602102), to cause transcriptional pausing of RNA polymerase II (see MIM 180660) (Narita et al., 2003
