Predicted to enable beta-catenin binding activity and cytoskeletal protein binding activity. Predicted to be involved in several processes, including positive regulation of dendritic spine development; positive regulation of smoothened signaling pathway; and regulation of hippo signaling. Predicted to act upstream of or within several processes, including animal organ development; apical protein localization; and protein localization to adherens junction. Predicted to be located in adherens junction; ciliary basal body; and postsynaptic density. Orthologous to human DLG5 (discs large MAGUK scaffold protein 5).
