DescriptionMouse monoclonal  to NCOR2 / SMRT
Tested applicationsSuitable for: ChIP, IHC-Fr, WB, Flow Cyt, IP, IHC-Pmore details
Species reactivityReacts with: Human
- HeLa cell extract
In ChIP ab2780 gives a maximum at 60 min (more than 60%) whereas ab2781 gives a minimum (around 5%) at this time and ab 2780 gives a minimum (less than 5%) at 30 min whereas ab2781 gives a maximum (50%). This protein is corepressor of the nuclear hormone receptors and is not supposed to be recruited in presence of the hormone (here oestrogen), and should be maximal before induction, which is not the case here for both antibodies!

Primary antibody notesSteroid and thyroid hormones and retinoic acid regulate a complex array of gene expression activity via intracellular receptor transcription factors belonging to the ligand-dependent nuclear receptor superfamily. Adding to the complexity of function of these transcription factors are associated proteins known as coactivators and corepressors which, as their names suggest, enhance or depress transcription activity of the nuclear receptor with which they associate. Silencing Mediator of Retinoic acid & Thyroid hormone receptor (SMRT) and nuclear receptor corepressor (N-CoR) are related transcriptional corepressors which contain two distinct domains capable of interacting with unliganded nuclear receptors to repress their basal transcriptional activity.

Our Abpromise guarantee covers the use of ab2781 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ChIP||Use at an assay dependent concentration.|
|IHC-Fr||Use at an assay dependent concentration.|
|WB||Use a concentration of 4 µg/ml. Detects a band of approximately 250, 220 kDa (predicted molecular weight: 274 kDa).Can be blocked with Retinoic Acid Receptor alpha peptide (ab4910).|
|Flow Cyt||Use 2µg for 106 cells.
ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
|IP||Use at an assay dependent concentration.|
|IHC-P||Use at an assay dependent concentration.|
FunctionTranscriptional corepressor of NR4A2/NURR1 and acts through histone deacetylases (HDACs) to keep promoters of NR4A2/NURR1 target genes in a repressed deacetylated state (By similarity). Mediates the transcriptional repression activity of some nuclear receptors by promoting chromatin condensation, thus preventing access of the basal transcription. Isoform 1 and isoform 5 have different affinities for different nuclear receptors.
Tissue specificityUbiquitous. High levels of expression are detected in lung, spleen and brain.
Sequence similaritiesBelongs to the N-CoR nuclear receptor corepressors family.
Contains 2 SANT domains.
DomainThe N-terminal region contains repression functions that are divided into three independent repression domains (RD1, RD2 and RD3). The C-terminal region contains the nuclear receptor-interacting domains that are divided in two separate interaction domains (ID1 and ID2).
The two interaction domains (ID) contain a conserved sequence referred to as the CORNR box. This motif is required and sufficient to permit binding to unligated TR and RARS. Sequences flanking the CORNR box determine nuclear hormone receptor specificity.

Overlay histogram showing HeLa cells stained with ab2781 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2781, 2µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
