GPR37 Proteins and Enzymes

GPR37 is an Orphan-A GPCR with an unknown ligand. GPR37 was recently identified as the PAEL receptor, a Parkin substrate involved in autosomal recessive juvenile Parkinson's (PDJ) disease. The PAEL receptor becomes unfolded, insoluble, and ubiquitinated when overexpressed, leading to unfolded protein-induced cell death. When the PAEL receptor is ubiquitinated by Parkin, it gets degraded, resulting in the suppression of cell death. The insoluble form of the PAEL receptor accumulates in the ...
