**Background of DDH2 Recombinant Protein**
DDH2 (Dihydrodiol Dehydrogenase 2), also known as carbonyl reductase 1 (CBR1), is a NADPH-dependent enzyme belonging to the short-chain dehydrogenase/reductase (SDR) superfamily. It plays a critical role in the metabolism of endogenous and exogenous compounds, including steroids, prostaglandins, and xenobiotics. DDH2 catalyzes the reduction of carbonyl groups in various substrates, contributing to detoxification pathways, drug metabolism, and the regulation of bioactive molecules. Its involvement in the inactivation of chemotherapeutic agents (e.g., anthracyclines) and the modulation of reactive aldehydes underscores its biomedical relevance.
Recombinant DDH2 protein is engineered using genetic cloning techniques, where the *DDH2* gene is expressed in heterologous systems like *E. coli* or mammalian cells. This allows large-scale production of the purified, functional enzyme for research and therapeutic applications. The recombinant form retains the enzymatic activity of native DDH2. enabling studies on its structural properties, substrate specificity, and interaction with inhibitors or activators.
Research on DDH2 recombinant protein has expanded due to its potential implications in cancer therapy, neurodegenerative diseases, and metabolic disorders. For instance, its role in mitigating oxidative stress by reducing cytotoxic aldehydes links it to neuroprotection, while its impact on drug resistance highlights its dual role in oncology. Additionally, DDH2 polymorphisms have been associated with variable drug responses, driving interest in personalized medicine.
Overall, DDH2 recombinant protein serves as a vital tool for elucidating biochemical pathways, developing targeted therapies, and exploring enzyme-driven mechanisms in health and disease. Its versatility continues to make it a focal point in both academic and pharmaceutical research.
