Active Recombinant Full Length Human ERG Protein, C-Flag-tagged

• Cat.No.: ERG-37HFL
• Product Overview: Recombinant Full Length Human ERG Protein, fused to Flag-tag at C-terminus, was expressed in Mammalian cells.

Specification

• Description: This gene encodes a member of the erythroblast transformation-specific (ETS) family of transcriptions factors. All members of this family are key regulators of embryonic development, cell proliferation, differentiation, angiogenesis, inflammation, and apoptosis. The protein encoded by this gene is mainly expressed in the nucleus. It contains an ETS DNA-binding domain and a PNT (pointed) domain which is implicated in the self-association of chimeric oncoproteins. This protein is required for platelet adhesion to the subendothelium, inducing vascular cell remodeling. It also regulates hematopoesis, and the differentiation and maturation of megakaryocytic cells. This gene is involved in chromosomal translocations, resulting in different fusion gene products, such as TMPSSR2-ERG and NDRG1-ERG in prostate cancer, EWS-ERG in Ewing's sarcoma and FUS-ERG in acute myeloid leukemia. More than two dozens of transcript variants generated from combinatorial usage of three alternative promoters and multiple alternative splicing events have been reported, but the full-length nature of many of these variants has not been determined.
• Source: Mammalian cells
• Species: Human
• Tag: Flag
• Form: 25 mM Tris HCl, pH 7.3, 100 mM glycine, 10% glycerol.
• Bio-activity: Varying amounts of human ERG expressed in HEK293 cells was incubated for one hour with wild-type or mutant biotinylated oligonucleotide (1 pmole/ul) in the presence of 25 ug/ml poly dI:dC. The reaction mixture was subsequently transferred to a microplate containing 2500 Luminex beads coupled with anti-ERG monoclonal antibody 2G8. The ERG-oligo complexes were captured onto the antibody-coated beads for two hours at room temperature with shaking. The beads were then washed, and the biotin was detected with streptavidin-phycoerythrin for 30 minutes. The beads were washed again and the fluorescent intensity was read in the Luminex instrument. The wild-type oligonucleotide carried ACCGGAAGT consensus binding sequence while the mutant oligonucleotide was identical except for a 2-base mutation in the consensus binding region, ACCCCAAGT.
  ELISA capture for autoantibodies.
