Is predicted to encode a protein with the following domains: P-loop containing nucleoside triphosphate hydrolase; L27 domain superfamily; PDZ superfamily; L27 domain; PDZ domain; Guanylate kinase/L-type calcium channel beta subunit; SH3-like domain superfamily; L27-1; Guanylate kinase; SH3 domain; and L27_1. Is an ortholog of C. elegans dlg-1. In C. elegans, dlg-1 is involved in embryo development and zonula adherens assembly.
