Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IHC-P=Immunohistochemistry (Paraffin), ChIP=Chromatin IP
Specificity / Sensitivity
RBPSUH (D10A4) XP® Rabbit mAb recognizes endogenous levels of total RBPSUH protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gln110 of human RBPSUH protein.
Western blot analysis of extracts from various cell lines using RBPSUH (D10A4) XP® Rabbit mAb.
CUTLL1 cells were cultured in media with γ-secretase inhibitor (1 μM, 3 d) and then either harvested immediately (left panel) or washed and cultured in fresh media for 3 h (right panel). Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 cells and 10 µl of RBPSUH (D10A4) XP® Rabbit mAb or 2 µl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using human HES1 promoter primers, SimpleChIP® Human HES4 Promoter Primers #7273, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

RBPSUH (Recombining Binding Protein, SUppressor of Hairless), also termed RBP-J or CSL, is the DNA-binding component of the transcription complex regulated by canonical Notch signaling. In the absence of Notch activation, RBPSUH suppresses target gene expression through interactions with a co-repressor complex containing histone deacetylase. Upon activation of Notch receptors, the Notch intracellular domain (NICD) translocates to the nucleus and binds to RBPSUH. This displaces the co-repressor complex and replaces it with a transcription activation complex that includes Mastermind-like (MAML) proteins and histone acetylase p300, leading to transcriptional activation of Notch target genes (1-3). RBPSUH is also the DNA-binding partner for Epstein-Barr virus (EBV) nuclear antigen 2 (EBNA2), a protein critical for latent viral transcription and immortalization of EBV-infected B cells (4,5).
