DDIT3 reduces DNA-binding activity of C/EBP and lap by forming heterodimers which don’t bind DNA. DDIT3, also known as GADD153, is a basic domain-leucine zipper(bZIP) transcription factor of C/EBP family. DDIT3 protein is up-regulated by several stresses, such as amino acid or glucose starvation, endoplasmic reticulum (ER) stress, osmotic stress and hypoxia. DDIT3 protein is invloved in ER stress-mediated apoptosis and in disease including diabetes, brain ischemia and neurodegenerative disease. DDIT3 plays a role in asoprisnil-induced apoptosis. Hypoglycaemia-induced necrotic cell death of neuroblastoma cells is an active process mediated via the induction of the transcription factor DDIT3. DDIT3 plays an important role in melanoma progression. HRG stimulation of mammary epithelial cells induces the expression of DDIT3 mRNA and protein and transcription of DDIT3 promoter.

DDIT3 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 189 amino acids and having a molecular mass of 21 kDa. The DDIT3 protein is fused to a 20 amino acids His tag at N-terminus.
The DDIT3 is purified by proprietary chromatographic techniques.
