Purification notesab58648 was purified using protein G column chromatography from culture supernatant of hybridoma cultured in a medium containing bovine IgG-depleted (approximately 95%) fetal bovine serum and filtered through a 0.22µm membrane.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Application notesDot: Use at an assay dependent dilution.
WB: Use at an assay dependent dilution. Detects a band of approximately 33 kDa (the immunising fragment) (predicted molecular weight: 53 kDa for full length protein).
Not yet tested in other applications.

FunctionOrphan nuclear receptor. Binds the IR7 element in the promoter of its own gene in an autoregulatory negative feedback mechanism. Primarily repressor of a broad range of genes. Binds to hormone response elements (HREs) consisting of two 5'-AGGTCA-3' half site direct repeat consensus sequences. Together with NR2C2, forms the core of the DRED (direct repeat erythroid-definitive) complex that represses embryonic and fetal globin transcription. Also activator of OCT4 gene expression. May be involved in stem cell proliferation and differentiation. Mediator of retinoic acid-regulated preadipocyte proliferation.
Sequence similaritiesBelongs to the nuclear hormone receptor family. NR2 subfamily. Contains 1 nuclear receptor DNA-binding domain.
Post-translational modificationsSumoylation requires both PIAS1 and UBE2I. Sumoylation appears to dissociate NR2C1 from the PML nuclear bodies. Enhances the interaction with NRIP1 but inhibits interaction with KAT2B. In proliferating cells, stimulation by all-trans retinoic acid, activation of MAPK1-mediated phosphorylation and recruitment to PML bodies with subsequent sumoylation, suppresses OCT4 expression. Phosphorylated on several serine and threonine residues. Phosphorylation on Thr-222, stimulated by all-trans retinoic acid (atRA) mediates PML location and sumoylation in proliferating cells which then modulates its association with effector molecules, KAT2B and NRIP1. Phosphorylation on Ser-581 by PKC is important for protein stability and function as activator of RARB.
Cellular localizationNucleus. Nucleus > PML body. Recruited by HDAC3, after all-trans retinoic acid stimulated MAPK1-mediated Thr-223 phosphorylation, to PML bodies for subsequent sumoylation.
