GPR175. a member of the G protein-coupled receptor (GPCR) superfamily, is an orphan receptor with limited functional characterization. Classified under the Class A GPCR subfamily, it shares structural hallmarks such as seven transmembrane domains but lacks a confirmed endogenous ligand. The human GPR175 gene is located on chromosome 2q14.3 and encodes a protein predominantly expressed in the central nervous system, endocrine tissues, and gastrointestinal tract, suggesting roles in neuroendocrine regulation and metabolic processes. Phylogenetically, it clusters closely with lipid-sensing receptors like GPR119 and GPR142. though its signaling mechanisms remain unclear.
Recombinant human GPR175 protein is typically produced using mammalian or insect cell systems to ensure proper post-translational modifications. These systems enable structural studies and ligand screening via biophysical assays (e.g., thermal stability shifts) or cell-based cAMP/β-arrestin recruitment assays. Despite being an understudied target, interest in GPR175 has grown due to genomic associations with metabolic disorders and cancer. Its overexpression in pancreatic tumors and potential linkage to Wnt/β-catenin pathways highlight therapeutic possibilities. Current research focuses on deorphanization efforts and elucidating its role in energy homeostasis, making recombinant GPR175 critical for probing its pathophysiology and drug discovery pipelines.
