For Research Use Only. Not for use in diagnostic procedures.

Polyclonal

Rabbit

The antibody detects endogenous levels of 53BP1 only when phosphorylated at serine 25.

Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy usi

Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.

1.0 mg/ml (lot specific)

Store at -20 degree C

Small volumes of anti-53BP1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Plays a key role in the response to DNA damage. May have a role in checkpoint signaling during mitosis. Enhances TP53-mediated transcriptional activation.

TP53B_HUMAN

53BP1: a DNA damage checkpoint protein that interacts with HDAC4 protein to mediate the DNA damage response. Inhibits E2F1-mediated apoptosis in prostate cancer cells. Recruited to double strand breaks via the binding of its Tudor domain to dimethylated H3 K20. Asymmetrically dimethylated on Arg residues by PRMT1. Methylation is required for DNA binding. Binds to the central domain of p53. Interacts with Artemis. Interacts with histone H2AFX and this requires phosphorylation of H2AFX on S139. Interacts with histone H4 that has been dimethylated at K20. Has low affinity for histone H4 containing monomethylated K20. Does not bind histone H4 containing unmethylated or trimethylated K20. Has low affinity for histone H3 that has been dimethylated on K79. Does not bind unmethylated histone H3. Phosphorylated at basal level in the absence of DNA damage. Hyper-phosphorylated in an ATM-dependent manner in response to DNA damage induced by ionizing radiation. Hyper-phosphorylated in an ATR-dependent manner in response to DNA damage induced by UV irradiation. Two alternatively spliced human isoforms have been observed.
