GPR37 Protein Description

GPR37(cathepsin Z, Histidine-tagged) is an orphan receptor which belongs to the G-protein coupled receptor 1 family. It is an orphan receptor and may have a unique functional role in the central nervous system. GPR37, expressed at highest levels in human brain,spinal cord and at lower levels in testis, placenta, liver, with homology to bombesin receptor. When overexpressed in cells, tends to become insoluble and unfolded. Accumulation of the unfolded protein may lead to dopaminergic neuronal death in juvenile Parkinson disease. GPR37 forms a complex with PARK2, STUB1 and HSP70. The amount of STUB1 in the complex increases during ER stress. STUB1 promotes the dissociation of HSP70 from PARK2, thus facilitating PARK2-mediated GPR37 ubiquitination. It interacts with PACRG and is ubiquitinated by PARK2 in the presence of UBE2E1 and UBE2L3 in the endoplasmic reticulum. The unfolded form is specifically ubiquitinated by SYVN1, which promotes its proteasomal degradation and prevents neuronal cell death.
