Predicted to enable adrenomedullin receptor activity and calcitonin gene-related peptide receptor activity. Acts upstream of or within blood vessel morphogenesis; chloride ion homeostasis; and somitogenesis. Predicted to be located in membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including cardiovascular system; neural tube; pleuroperitoneal region; trunk; and ventral mesoderm. Human ortholog(s) of this gene implicated in hereditary lymphedema. Orthologous to human CALCRL (calcitonin receptor like receptor).
