Predicted to enable Wnt-protein binding activity. Predicted to be involved in several processes, including Wnt signaling pathway; negative regulation of DNA-binding transcription factor activity; and negative regulation of signal transduction. Predicted to act upstream of or within several processes, including negative regulation of JUN kinase activity; post-anal tail morphogenesis; and regulation of establishment of planar polarity. Predicted to be active in extracellular space. Orthologous to human SFRP5 (secreted frizzled related protein 5). [provided by Alliance of Genome Resources, Apr 2022]
