Enables Wnt-activated receptor activity. Acts upstream of or within several processes, including animal organ morphogenesis; hard palate development; and nervous system development. Predicted to be located in cytoplasm. Predicted to be active in plasma membrane. Predicted to be integral component of membrane. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in omodysplasia 2. Orthologous to human FZD2 (frizzled class receptor 2). [provided by Alliance of Genome Resources, Apr 2022]
