Predicted to enable Wnt-protein binding activity. Acts upstream of with a negative effect on canonical Wnt signaling pathway and non-canonical Wnt signaling pathway. Acts upstream of or within several processes, including camera-type eye morphogenesis; endodermal digestive tract morphogenesis; and positive regulation of signal transduction. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in several structures, including anterior neural keel; anterior neural rod; gut; immature eye; and nervous system. Orthologous to human SFRP5 (secreted frizzled related protein 5).
