Predicted to enable molecular adaptor activity and protein domain specific binding activity. Predicted to be a structural constituent of postsynaptic density. Predicted to be involved in several processes, including aggresome assembly; regulation of postsynaptic neurotransmitter receptor activity; and regulation of proteasomal protein catabolic process. Predicted to act upstream of or within chemical synaptic transmission. Located in postsynaptic density. Is expressed in hippocampus. Orthologous to human DLGAP1 (DLG associated protein 1).
