Predicted to enable several functions, including Wnt-protein binding activity; frizzled binding activity; and low-density lipoprotein particle receptor activity. Involved in several processes, including canonical Wnt signaling pathway; positive regulation of cytosolic calcium ion concentration; and response to peptide hormone. Located in neuronal cell body and synapse. Human ortholog(s) of this gene implicated in tooth agenesis. Orthologous to human LRP6 (LDL receptor related protein 6).
