**Background of SULT1C4 Recombinant Protein**
The SULT1C4 protein belongs to the sulfotransferase (SULT) family, a group of enzymes that catalyze the transfer of a sulfonyl group from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to various substrates, including hormones, neurotransmitters, drugs, and xenobiotics. This post-translational modification, known as sulfonation, plays a critical role in regulating the bioactivity, solubility, and excretion of endogenous and exogenous compounds. The SULT1 family, to which SULT1C4 belongs, is primarily involved in the sulfonation of small molecules, including thyroid hormones, phenolic compounds, and certain drugs.
SULT1C4. encoded by the *SULT1C4* gene, is a less well-characterized member compared to other SULT1 isoforms. It is expressed in fetal tissues, adult thyroid, kidney, and gastrointestinal tract, suggesting roles in developmental processes and organ-specific metabolism. Its substrates may include thyroid hormones, estrogens, and environmental procarcinogens, though its exact physiological and pathological functions remain under investigation. Recombinant SULT1C4 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to enable functional studies, structural analysis, and drug metabolism research.
Interest in SULT1C4 stems from its potential involvement in cancer progression, as altered sulfotransferase activity has been linked to hormone-dependent malignancies and detoxification pathways. Additionally, genetic polymorphisms in *SULT1C4* may influence individual responses to therapeutics or susceptibility to toxin-induced diseases. The recombinant protein serves as a tool to explore these mechanisms, aiding in the development of targeted therapies or biomarkers. Despite its emerging significance, further research is needed to fully elucidate its substrate specificity, regulatory pathways, and clinical relevance.
