Opioid Growth Factor Receptor (OGFR), also known as the zeta (ζ) opioid receptor, is a non-classical member of the opioid receptor family. Unlike traditional opioid receptors (μ, δ, κ), OGFR does not bind endogenous opioid peptides like enkephalins or beta-endorphin. Instead, it interacts specifically with Opioid Growth Factor (OGF), a naturally occurring peptide identified as methionine-enkephalin. OGFR is widely expressed in mammalian tissues, including the nervous, immune, and epithelial systems, and plays a critical role in regulating cell proliferation, tissue repair, and immune responses. Its involvement in cell cycle control—particularly through the cyclin-dependent kinase pathway—has made it a focus in cancer research, where OGF-OGFR signaling has been shown to inhibit tumor growth.
Recombinant OGFR proteins are engineered in vitro using expression systems like E. coli, yeast, or mammalian cells to produce purified, functional receptor variants. These proteins often include affinity tags (e.g., His-tag) for simplified purification and detection. Recombinant OGFR enables detailed studies of receptor-ligand interactions, structural characterization, and downstream signaling mechanisms. Researchers utilize it to explore therapeutic potential in conditions such as cancer, autoimmune disorders, and neurodegenerative diseases. For example, preclinical studies suggest OGF-OGFR axis modulation could enhance chemotherapy efficacy or mitigate neuropathic pain. The development of recombinant OGFR has also facilitated drug screening campaigns to identify small molecules targeting this receptor. Despite its therapeutic promise, OGFR's precise molecular structure and signaling crosstalk with classical opioid pathways remain under investigation, highlighting the importance of recombinant tools in elucidating its biological complexity.
