Enables identical protein binding activity; peptide hormone binding activity; and peptide receptor activity. Involved in several processes, including G protein-coupled receptor signaling pathway; negative regulation of adenylate cyclase activity; and positive regulation of nitric-oxide synthase activity. Located in membrane. Biomarker of diabetic retinopathy. Human ortholog(s) of this gene implicated in hypertension. Orthologous to human NPR3 (natriuretic peptide receptor 3).
