Predicted to enable several functions, including chloride ion binding activity; peptide receptor activity; and protein homodimerization activity. Involved in several processes, including negative regulation of cold-induced thermogenesis; osteoclast proliferation; and positive regulation of urine volume. Predicted to be located in membrane. Predicted to be part of protein-containing complex. Is expressed in several structures, including central nervous system; genitourinary system; gut; heart and pericardium; and lung. Used to study bone disease. Human ortholog(s) of this gene implicated in hypertension. Orthologous to human NPR3 (natriuretic peptide receptor 3). [provided by Alliance of Genome Resources, Apr 2022]
