GPR37 Protein, a receptor for prosaposin, undergoes endocytosis upon ligand binding, initiating an ERK phosphorylation cascade. It forms a complex with PRKN, STUB1, and HSP70, with STUB1 association increasing during ER stress. STUB1 facilitates HSP70 dissociation from PRKN, promoting PRKN-mediated ubiquitination of GPR37. GPR37 also interacts with PACRG, indicating a complex regulatory network in its cellular functions. GPR37 Protein, Human (HEK293, His) is the recombinant human-derived GPR37, expressed by HEK293, with C-His labeled tag.
Molecular Weight:
Approximately 30-45 kDa, based on SDS-PAGE under reducing conditions, due to the glycosylation .
