GPR37. also known as the parkin-associated endothelin-like receptor (Pael-R), is an orphan G protein-coupled receptor (GPCR) predominantly expressed in the central nervous system, particularly in oligodendrocytes, astrocytes, and neurons. It gained attention due to its association with Parkinson’s disease (PD), as accumulated GPR37 aggregates were identified in the brains of PD patients. While its endogenous ligand remains unclear, studies suggest interactions with neuropeptides like prosaposin and progastricsin. GPR37 is implicated in regulating cell survival, myelination, and dopamine signaling, though its precise physiological roles are still under investigation.
Recombinant GPR37 proteins are engineered to study its structure, function, and pathological mechanisms. These proteins are typically produced using heterologous expression systems, such as mammalian cells (HEK293) or insect cells (Sf9), to ensure proper folding and post-translational modifications. Purification often involves affinity tags (e.g., His-tag) and detergent solubilization to maintain stability. Recombinant GPR37 enables ligand-binding assays, receptor trafficking studies, and screening for potential therapeutic modulators.
Research highlights GPR37’s dual role in neurodegeneration and cancer. In PD models, GPR37 overexpression exacerbates neuronal toxicity, while its knockout exhibits neuroprotective effects. Conversely, GPR37 overexpression in glioblastoma promotes tumor growth, suggesting context-dependent signaling. Challenges remain in resolving its 3D structure and identifying natural ligands, limiting drug development. Recombinant protein tools are critical for unraveling GPR37’s signaling pathways (e.g., cAMP, MAPK) and validating its potential as a therapeutic target for neurological disorders or oncology. Ongoing studies aim to clarify its interactions with parkin and other PD-linked proteins, bridging molecular gaps in disease pathology.
