**Background of DHRS7 Recombinant Protein**
DHRS7 (Dehydrogenase/Reductase 7), a member of the short-chain dehydrogenase/reductase (SDR) superfamily, is an NADPH-dependent enzyme involved in redox reactions and metabolic pathways. It is encoded by the *DHRS7* gene located on human chromosome 14q11.2 and shares structural features typical of SDRs, including a conserved Rossmann fold for cofactor binding and a catalytic tetrad critical for substrate specificity.
Functionally, DHRS7 is implicated in retinoid metabolism, potentially regulating retinol (vitamin A) homeostasis by converting retinaldehyde to retinol. This activity links it to cellular processes such as differentiation, proliferation, and apoptosis. Additionally, DHRS7 may interact with cellular stress response pathways, including oxidative and endoplasmic reticulum stress, suggesting roles in maintaining cellular redox balance.
Research highlights its tissue-specific expression, with higher levels observed in the liver, kidney, and brain. Dysregulation of DHRS7 has been associated with pathologies such as cancer, metabolic disorders, and neurodegenerative diseases. For instance, reduced DHRS7 expression in hepatocellular carcinoma correlates with tumor progression, while its antioxidant properties may protect neurons in Alzheimer’s disease models.
Recombinant DHRS7 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), enables functional and structural studies. It serves as a tool to elucidate enzymatic mechanisms, screen inhibitors/activators, and explore therapeutic applications. Its recombinant form is critical for developing targeted therapies, particularly in diseases linked to retinoid dysregulation or oxidative stress. Ongoing studies aim to clarify its substrate spectrum and physiological partners, advancing its potential as a biomarker or drug target.
