GPR24. a member of the G protein-coupled receptor (GPCR) family, is classified within the rhodopsin-like subfamily and remains an orphan receptor due to its unidentified endogenous ligand. Structurally, it features seven transmembrane α-helices, a hallmark of GPCRs, which facilitate signal transduction across cell membranes via interactions with intracellular G proteins. The receptor is predominantly expressed in the brain, particularly in regions like the hypothalamus, pituitary gland, and limbic system, suggesting roles in neuroendocrine regulation, stress response, and circadian rhythm modulation.
Recombinant human GPR24 protein is engineered using genetic cloning techniques, often expressed in mammalian cell systems (e.g., HEK293) to ensure proper post-translational modifications and membrane localization. This recombinant form serves as a critical tool for studying ligand-receptor binding, downstream signaling pathways (e.g., cAMP or β-arrestin recruitment), and receptor activation mechanisms. Research implicates GPR24 in psychiatric disorders, including schizophrenia and bipolar disorder, due to its linkage to dysregulated neurodevelopmental processes. Additionally, studies propose its involvement in metabolic homeostasis, with potential ties to obesity and diabetes via interactions with melanocortin pathways. Despite progress, challenges persist in elucidating its precise physiological roles and therapeutic potential, partly due to the lack of validated ligands. Recombinant GPR24 thus remains a focus for drug discovery aimed at neurodegenerative and metabolic diseases.
