Enables Wnt-protein binding activity. Acts upstream of or within several processes, including cell proliferation in midbrain; embryonic morphogenesis; and establishment of body hair planar orientation. Located in apical plasma membrane; apicolateral plasma membrane; and endoplasmic reticulum membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in nonsyndromic congenital nail disorder 1. Orthologous to human FZD6 (frizzled class receptor 6). [provided by Alliance of Genome Resources, Apr 2022]
