Product Overview

Tag His
Host Species Human
Accession P53567
Synonym GPE1BP, IG/EBP-1
Background CEBPG, also known as CEBP gamma, is a transcription factor which belongs to the CEBP family. Members of this family regulate viral and cellular CCAAT/enhancer element-mediated transcription. CEBP proteins contain the bZIP region, which is characterized by two motifs in the C-terminal half of the protein: a basic region involved in DNA binding and a leucine zipper motif involved in dimerization. CEBPG binds to the enhancer element PRE-I of the IL-4 gene. It Might change the DNA-binding specificity of other transcription factors and recruit them to unusual DNA sites.
Description A DNA sequence encoding the human CEBPG (P53567) (Pro39-Asn147) was expressed with a His tag at the N-terminus.
Source E.coli
Predicted N Terminal His
AA Sequence Pro39-Asn147
Molecular Weight The recombinant human CEBPG consists of 124 a.a. and predicts a molecular mass of 14.1 KDa. It migrates as an approximately 16 KDa band in SDS-PAGE under reducing conditions.
Purity >90% as determined by SDS-PAGE
Endotoxin Please contact us for more information.

Formulation Lyophilized from sterile 50mM Tris, 10% glycerol, pH 8.0..
Stability The recombinant proteins are stable for up to 1 year from date of receipt at -70°C.
Usage For Research Use Only
Storage Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Target Details

Target Function Transcription factor that binds to the promoter and the enhancer regions of target genes. Binds to the enhancer element PRE-I (positive regulatory element-I) of the IL-4 gene. Binds to the promoter and the enhancer of the immunoglobulin heavy chain. Binds to GPE1, a cis-acting element in the G-CSF gene promoter.
Subcellular Location Nucleus.
Protein Families BZIP family, C/EBP subfamily

  1. These findings suggest that CEBPG may play an oncogenic role in BCP-ALL and relies on a mechanism different from CEBPA. PMID: 25669928
  2. High CEBPG expression correlated with poorer clinical prognoses in several human cancers, and C/EBP gamma depletion decreased proliferation and induced senescence in lung tumor cells. PMID: 23775115
  3. CEBPG mediates the myeloid differentiation arrest induced by CEBPA deficiency in acute myeloid leukemia. PMID: 23160200
  4. C/EBPgamma positively regulates wound repair both in vitro and in vivo, at least in part, by affecting EGFR signaling. PMID: 22437320
  5. Ig/EBP (C/EBPgamma)is constitutively multiubiquitinated & then degraded by the proteasome. Ubiquitination and degradation are suppressed by forming dimers through the leucine zipper domains. PMID: 12618752
  6. CEBPG is the transcription factor primarily responsible for regulating transcription of key antioxidant and DNA repair genes in non-bronchogenic carcinoma individuals PMID: 16255782
  7. CEBPG regulates ERCC5 expression and this regulation is modified by E2F1/YY1 interactions. PMID: 17893230

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
