Summary: Predicted to enable guanylate kinase activity and protein kinase binding activity. Involved in embryo development and zonula adherens assembly. Located in adherens junction and apical junction complex. Is expressed in several structures, including epithelial cell; germ line; intestine; pharynx; and vulva. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder; invasive ductal carcinoma; and non-syndromic X-linked intellectual disability 90. Orthologous to several human genes including DLG1 (discs large MAGUK scaffold protein 1); DLG3 (discs large MAGUK scaffold protein 3); and DLG4 (discs large MAGUK scaffold protein 4).
