**Background of NDRG1 Recombinant Protein**
NDRG1 (N-myc downstream-regulated gene 1) is a member of the NDRG family, comprising four isoforms (NDRG1-4) that play diverse roles in cellular processes. Initially identified as a stress-responsive gene regulated by N-myc and hypoxia-inducible factor 1-alpha (HIF-1α), NDRG1 is implicated in cell differentiation, proliferation, and apoptosis. It functions as a metastasis suppressor in certain cancers, though its role varies contextually, showing both tumor-promoting and tumor-suppressive activities depending on tissue type and molecular environment.
Structurally, NDRG1 contains an α/β hydrolase-fold domain, though it lacks enzymatic activity. Its expression is upregulated under hypoxic conditions, DNA damage, or metal ion stress (e.g., iron deprivation), linking it to metabolic regulation and metal homeostasis. Dysregulation of NDRG1 is associated with cancer progression, neurodegenerative diseases (e.g., Alzheimer’s), and peripheral neuropathies, highlighting its biomedical relevance.
Recombinant NDRG1 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells*) to study its molecular mechanisms, interactions, and therapeutic potential. Purified through affinity chromatography (e.g., His-tag systems), it serves as a tool for *in vitro* assays, antibody production, and drug screening. Research utilizing recombinant NDRG1 has advanced understanding of its role in signaling pathways (e.g., Wnt/β-catenin, TGF-β), metastasis inhibition, and response to chemotherapeutic agents.
Despite progress, ambiguities remain regarding its precise molecular targets and context-dependent functions, driving ongoing studies to exploit NDRG1 as a diagnostic marker or therapeutic target in diseases like cancer and neurodegeneration.
