Enables Wnt-protein binding activity and frizzled binding activity. Acts upstream of or within several processes, including establishment of planar polarity involved in neural tube closure; inner ear development; and ossification involved in bone remodeling. Located in cytoplasm. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; sensory organ; and skeleton. Human ortholog(s) of this gene implicated in Barrett's esophagus. Orthologous to human CTHRC1 (collagen triple helix repeat containing 1). [provided by Alliance of Genome Resources, Apr 2022]
