Predicted to enable G protein-coupled peptide receptor activity; peptide binding activity; and prosaposin receptor activity. Predicted to be involved in several processes, including adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway; negative regulation of hydrogen peroxide-induced cell death; and positive regulation of MAPK cascade. Predicted to act upstream of or within negative regulation of cell differentiation; negative regulation of smoothened signaling pathway; and positive regulation of cerebellar granule cell precursor proliferation. Predicted to be located in ciliary membrane. Predicted to be integral component of membrane. Predicted to be part of receptor complex. Predicted to be active in plasma membrane. Orthologous to human GPR37L1 (G protein-coupled receptor 37 like 1). [provided by Alliance of Genome Resources, Apr 2022]
