Enables Wnt-activated receptor activity; identical protein binding activity; and protein heterodimerization activity. Involved in several processes, including G protein-coupled receptor signaling pathway coupled to cGMP nucleotide second messenger; Wnt signaling pathway; and cellular response to vitamin D. Located in plasma membrane. Biomarker of myocardial infarction. Human ortholog(s) of this gene implicated in omodysplasia 2. Orthologous to human FZD2 (frizzled class receptor 2).
