**Background of TR4 Recombinant Protein**
TR4 (Testicular Receptor 4), also known as Nuclear Receptor Subfamily 2 Group C Member 2 (NR2C2), is a member of the nuclear receptor superfamily, which regulates gene expression in response to signaling pathways. It functions as a ligand-dependent transcription factor, though its endogenous ligands remain poorly characterized. TR4 plays critical roles in diverse physiological processes, including metabolism, development, and circadian rhythm regulation. It is expressed in various tissues, such as the brain, liver, and reproductive organs, highlighting its broad functional relevance.
The recombinant TR4 protein is engineered in vitro using genetic engineering techniques, enabling large-scale production for research and therapeutic applications. Typically produced in bacterial or mammalian expression systems, recombinant TR4 retains the ability to bind DNA and regulate target genes, making it valuable for studying its molecular mechanisms. Purification methods, such as affinity chromatography, ensure high purity and biological activity.
Research on TR4 has linked it to diseases like cancer, metabolic syndrome, and neurodegenerative disorders. For example, TR4 modulates lipid and glucose homeostasis, suggesting its role in diabetes and obesity. In cancer, TR4 exhibits dual roles, acting as an oncogene or tumor suppressor depending on the tissue context. Recombinant TR4 protein facilitates structural studies, drug screening, and antibody development, aiding in the exploration of its therapeutic potential.
Despite progress, challenges remain, including understanding tissue-specific TR4 interactions and identifying its ligands. Advances in recombinant protein technology continue to drive discoveries, positioning TR4 as a promising target for precision medicine and disease intervention.
