**Background of NGFIB Recombinant Protein**
NGFIB (nerve growth factor-induced clone B), also known as NR4A1 or Nur77. is a member of the NR4A subfamily of nuclear receptors. Initially identified as an immediate-early response gene induced by nerve growth factor (NGF) in pheochromocytoma cells, it plays critical roles in cellular processes such as proliferation, apoptosis, differentiation, and inflammation. Unlike classical nuclear receptors, NR4A1 lacks a canonical ligand-binding domain and functions in a ligand-independent manner, acting primarily through transcriptional regulation.
The recombinant NGFIB protein is engineered to enable detailed study of its structure, function, and interactions. Produced via bacterial or mammalian expression systems, recombinant NGFIB retains key functional domains, including the DNA-binding domain (DBD) and activation function domain (AF-1), allowing researchers to investigate its role in signaling pathways, such as the NF-κB and MAPK cascades.
Research highlights its involvement in diseases like cancer, metabolic disorders, and neurodegenerative conditions. For example, NGFIB regulates apoptosis in cancer cells by modulating mitochondrial pathways, making it a potential therapeutic target. In neuroscience, it influences neuronal survival and synaptic plasticity.
Recombinant NGFIB is widely utilized in *in vitro* assays, protein interaction studies, and drug screening. Its production often involves tags (e.g., His-tag) for purification and detection. Challenges remain in understanding its post-translational modifications and context-dependent functions. Continued exploration of NGFIB recombinant protein aims to unlock its therapeutic potential and mechanistic insights into cellular homeostasis and disease pathogenesis.
