Enables frizzled binding activity and transcription corepressor activity. Involved in several processes, including paramesonephric duct development; positive regulation of cellular component biogenesis; and regulation of cellular biosynthetic process. Acts upstream of or within several processes, including animal organ development; negative regulation of signal transduction; and renal vesicle induction. Located in cell surface; extracellular matrix; and extracellular space. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; limb; and sensory organ. Human ortholog(s) of this gene implicated in Mullerian aplasia and hyperandrogenism. Orthologous to human WNT4 (Wnt family member 4). [provided by Alliance of Genome Resources, Apr 2022]
