Proopiomelanocortin (POMC) is a multifunctional precursor protein encoded by the *POMC* gene, playing a central role in endocrine and neurological regulation. Initially synthesized in the anterior pituitary, hypothalamus, and peripheral tissues, POMC undergoes tissue-specific proteolytic cleavage to yield biologically active peptides, including adrenocorticotropic hormone (ACTH), β-endorphin, and α-melanocyte-stimulating hormone (α-MSH). These peptides regulate diverse physiological processes such as stress response, energy homeostasis, pain modulation, and pigmentation.
Recombinant POMC protein, produced via genetic engineering in heterologous systems (e.g., *E. coli*, yeast, or mammalian cells), enables controlled study of its processing and functions. Its development addresses challenges in isolating natural POMC due to low abundance and complex post-translational modifications. Recombinant technology allows customization, such as introducing tags for purification or mutations to study structure-activity relationships.
Research on recombinant POMC has advanced understanding of metabolic disorders (e.g., obesity linked to POMC mutations) and adrenal insufficiency. For instance, synthetic ACTH analogs derived from recombinant POMC are used diagnostically and therapeutically. Additionally, α-MSH analogs show potential in treating inflammation and metabolic syndromes. However, challenges persist in replicating native post-translational modifications critical for bioactivity, driving optimization of expression systems.
Current applications extend to drug discovery, antibody production, and mechanistic studies of POMC-derived peptides in neurodegenerative diseases and cancer. As a research tool, recombinant POMC facilitates high-throughput screening for modulators of melanocortin receptors, key targets in obesity therapy. Ongoing efforts focus on improving recombinant protein yield, stability, and functional fidelity to bridge gaps between *in vitro* models and clinical outcomes. This technology remains pivotal in unraveling POMC's multifaceted roles and translating findings into therapeutic innovations.
