**Background of MT1 Recombinant Protein**
MT1 (Metallothionein-1) is a small, cysteine-rich protein belonging to the metallothionein family, which plays critical roles in metal ion homeostasis, detoxification, and cellular protection against oxidative stress. These proteins are characterized by their high affinity for binding essential (e.g., zinc, copper) and toxic (e.g., cadmium, mercury) heavy metals through conserved cysteine residues. MT1 isoforms, including MT1A, MT1B, and others, are encoded by a cluster of genes located on human chromosome 16 and are ubiquitously expressed, particularly in the liver, kidneys, and brain.
The primary function of MT1 involves regulating intracellular metal ion distribution, scavenging reactive oxygen species (ROS), and mitigating metal toxicity. Its expression is induced by heavy metals, glucocorticoids, and oxidative stress, mediated through metal-responsive transcription factor 1 (MTF-1) and antioxidant response elements. Dysregulation of MT1 has been linked to neurodegenerative diseases, cancer progression, and metal-related pathologies, highlighting its biomedical relevance.
Recombinant MT1 proteins are produced using heterologous expression systems (e.g., *E. coli* or yeast) to study their structure-function relationships, metal-binding properties, and therapeutic potential. The recombinant form retains native folding and metal-binding capacity, enabling applications in biomedical research, such as developing metal chelation therapies, antioxidant agents, or biomarkers for metal exposure. Additionally, MT1 recombinant proteins serve as tools to explore mechanisms underlying metal metabolism disorders and oxidative stress-related diseases. Advances in recombinant technology have enhanced the accessibility of MT1 for both basic research and clinical applications, reinforcing its importance in cellular biochemistry and toxicology.
