NCBI Description

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 [PubMed 12612062]).[supplied by OMIM, Mar 2008]

Uniprot Description

COBRA1: a subunit of the multisubunit transcription elongation factor NELF (negative elongation factor). May be involved in transcriptional pausing of RNA polymerase II (RNAPII). Interacts with the first BRCT repeat of BRCA1.

Protein type: Transcription, coactivator/corepressor; Nuclear receptor co-regulator

Chromosomal Location of Human Ortholog: 9q34

Cellular Component: cytoplasm; nucleoplasm

Molecular Function: protein binding

Biological Process: positive regulation of viral transcription; RNA elongation from RNA polymerase II promoter; transcription from RNA polymerase II promoter

Product Notes

The COBRA1 nelfb (Catalog #AAA7041834) is an Antibody Pair produced from Capture: Rabbit Detection: Rabbit and is intended for research purposes only. The product is available for immediate purchase. The COBRA1 Antibody Pair reacts with Mouse, Bovine, Horse, Pig, Dog, Goat and may cross-react with other species as described in the data sheet. AAA Biotech's COBRA1 can be used in a range of immunoassay formats including, but not limited to, Sandwich ELISA (EIA). We recommend using the capture antibody at a concentration of 0.2ug/ml and the detection antibody at a concentration of 0.25ug/ml. Researchers should empirically determine the suitability of the COBRA1 nelfb for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "COBRA1, Polyclonal Antibody Pair" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
