**Background of TACR3 Recombinant Protein**
TACR3 (tachykinin receptor 3), also known as NK3R, is a G protein-coupled receptor (GPCR) that primarily binds neurokinin B (NKB), a member of the tachykinin neuropeptide family. It plays critical roles in regulating neuroendocrine functions, including reproductive health, stress responses, and energy homeostasis. TACR3 is widely expressed in the central nervous system (CNS), particularly in hypothalamic regions, and interacts with the Kisspeptin system to modulate gonadotropin-releasing hormone (GnRH) secretion, essential for puberty onset and fertility.
Recombinant TACR3 protein is engineered in vitro using expression systems (e.g., mammalian, insect, or bacterial cells) to produce purified, functional receptor proteins for research. This technology enables the study of TACR3’s structure, ligand-binding mechanisms, and downstream signaling pathways (e.g., phospholipase C activation). Researchers leverage recombinant TACR3 to screen therapeutic compounds targeting disorders linked to receptor dysfunction, such as hypogonadotropic hypogonadism, polycystic ovary syndrome (PCOS), or mood disorders.
Interest in TACR3 has grown due to its association with rare genetic mutations causing delayed puberty and infertility. Preclinical studies using recombinant proteins or receptor antagonists/agonists highlight its potential in treating reproductive and metabolic diseases. However, challenges remain in optimizing receptor stability and activity in vitro. Ongoing research aims to clarify TACR3’s role in broader physiological networks and its therapeutic applicability, positioning it as a key target in neuroendocrinology and drug discovery.
