Nuclear receptor-interacting protein 1 (NRIP1), also known as receptor-interacting protein 140 (RIP140), is a multifaceted transcriptional coregulator involved in nuclear receptor-mediated signaling pathways. Discovered in the 1990s, NRIP1 interacts with various nuclear receptors, including estrogen receptors (ERs), retinoid receptors, and thyroid hormone receptors, modulating their transcriptional activity. It functions as both a coactivator and corepressor depending on cellular context and receptor type, influencing diverse biological processes such as energy metabolism, reproduction, and circadian rhythm regulation.
Structurally, NRIP1 contains multiple nuclear receptor-binding motifs and recruitment domains for chromatin-modifying enzymes. Its role in metabolic homeostasis has drawn significant attention, particularly in adipogenesis, lipid storage, and glucose utilization. Studies link NRIP1 dysregulation to metabolic disorders, cancer progression, and reproductive abnormalities. For instance, it promotes tumor growth in hormone-dependent cancers by enhancing oncogenic signaling. Recombinant NRIP1 protein, produced using expression systems like E. coli or mammalian cells, enables in vitro studies of protein interactions, transcriptional mechanisms, and drug screening. Ongoing research focuses on targeting NRIP1 pathways for therapeutic interventions in obesity, diabetes, and cancer.
