Enables guanylate cyclase activity; identical protein binding activity; and natriuretic peptide receptor activity. Acts upstream of or within several processes, including bone development; negative regulation of meiotic cell cycle; and negative regulation of oocyte maturation. Predicted to be integral component of plasma membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; sensory organ; and skeleton. Used to study achondroplasia; acromesomelic dysplasia, Maroteaux type; and bone development disease. Human ortholog(s) of this gene implicated in Miura type epiphyseal chondrodysplasia; acromesomelic dysplasia, Maroteaux type; and essential hypertension. Orthologous to human NPR2 (natriuretic peptide receptor 2). [provided by Alliance of Genome Resources, Apr 2022]
