**Background of ESRRA Recombinant Protein**
Estrogen-related receptor alpha (ESRRA), a member of the nuclear receptor superfamily, functions as a transcription factor regulating genes involved in energy metabolism, mitochondrial biogenesis, and cellular stress responses. Unlike classical estrogen receptors, ESRRA does not bind endogenous estrogen but is constitutively active, interacting with coactivators or corepressors to modulate target gene expression. It plays critical roles in metabolic homeostasis, oxidative phosphorylation, and adaptive responses to low-energy conditions, linking cellular energy status to transcriptional regulation.
ESRRA recombinant protein is engineered through molecular cloning and expression in systems like *E. coli* or mammalian cells, ensuring high purity and bioactivity. This protein typically retains functional domains, including the DNA-binding domain (DBD) for target gene recognition and the ligand-binding domain (LBD), which facilitates interactions with synthetic ligands or coregulators. Despite lacking a known natural ligand, ESRRA’s activity can be modulated by synthetic agonists (e.g., GSK4716) or inverse agonists (e.g., XCT790), making the recombinant protein valuable for studying receptor regulation.
Research applications include investigating ESRRA’s role in diseases such as cancer, metabolic disorders, and neurodegenerative conditions. Dysregulation of ESRRA is linked to tumor progression, insulin resistance, and mitochondrial dysfunction. The recombinant protein enables *in vitro* studies on its DNA-binding properties, protein-protein interactions, and screening of therapeutic compounds. Its availability supports structural studies (e.g., X-ray crystallography) and drug discovery efforts aimed at targeting ESRRA pathways. Overall, ESRRA recombinant protein serves as a crucial tool for dissecting its biological functions and therapeutic potential.
