Recombinant human ESRRBL1 (Estrogen-Related Receptor Beta-Like 1) protein is a genetically engineered form of the ESRRBL1 protein, designed for functional and structural studies. ESRRBL1 belongs to the nuclear receptor superfamily, which regulates gene expression by binding to specific DNA response elements. Although its exact physiological role remains less characterized compared to its homolog ESRRB (Estrogen-Related Receptor Beta), ESRRBL1 is hypothesized to participate in metabolic regulation, cellular differentiation, and energy homeostasis. It shares a conserved DNA-binding domain (DBD) and ligand-binding domain (LBD) with other nuclear receptors, enabling interactions with co-regulators and potential ligands.
Produced via bacterial or mammalian expression systems, recombinant ESRRBL1 retains post-translational modifications critical for its activity, facilitating in vitro assays like electrophoretic mobility shift assays (EMSAs), co-immunoprecipitation, or transcriptional activation studies. Its recombinant form is particularly valuable for investigating molecular mechanisms in diseases linked to nuclear receptor dysfunction, such as metabolic syndromes, cancers, or neurodegenerative disorders. Additionally, it aids in screening synthetic ligands or inhibitors for therapeutic development. Despite functional overlap with ESRRB, unique tissue-specific expression patterns and target genes of ESRRBL1 underscore its distinct biological significance, warranting further exploration.
