Predicted to be involved in negative regulation of canonical Wnt signaling pathway. Predicted to act upstream of or within several processes, including dendrite arborization; olfactory learning; and positive regulation of intracellular signal transduction. Predicted to be located in axon terminus; dendrite; and endoplasmic reticulum. Predicted to be active in plasma membrane. Orthologous to human TPBG (trophoblast glycoprotein).
