**Background of MT1A Recombinant Protein**
Metallothionein 1A (MT1A) is a small, cysteine-rich protein belonging to the metallothionein (MT) family, which plays critical roles in metal ion homeostasis, detoxification of heavy metals, and protection against oxidative stress. MT1A is encoded by the *MT1A* gene located on human chromosome 16 and is highly conserved across species. Its structure includes multiple cysteine residues (20 out of ~61 amino acids) arranged in characteristic motifs, enabling strong binding to divalent metal ions like zinc, copper, and cadmium. This metal-binding capacity underpins its involvement in regulating cellular metal distribution, scavenging reactive oxygen species (ROS), and mitigating metal toxicity.
Recombinant MT1A protein is produced using biotechnological platforms, such as *E. coli* or yeast expression systems, to ensure high purity and scalability. These systems allow precise control over post-translational modifications and metal-loading states, making recombinant MT1A valuable for research and industrial applications. The protein is often purified via affinity chromatography and validated using techniques like SDS-PAGE, Western blotting, and mass spectrometry to confirm integrity and functionality.
In biomedical research, MT1A recombinant protein is widely used to study mechanisms of metal-related diseases (e.g., neurodegenerative disorders, cancer) and oxidative stress pathways. It also serves as a tool in environmental toxicology to assess heavy metal detoxification processes. Additionally, its antioxidant properties have spurred interest in therapeutic applications, including potential use in treating metal overload conditions or as a protective agent against radiation or chemotherapy-induced cellular damage.
Despite its promise, challenges remain in optimizing recombinant production to maintain native folding and metal-binding activity. Ongoing studies aim to refine expression systems and explore engineered variants for enhanced stability or targeted functions, broadening MT1A's utility in both basic science and clinical contexts.
