Summary: Enables PDZ domain binding activity; ionotropic glutamate receptor binding activity; and protein phosphatase binding activity. A structural constituent of postsynaptic density. Predicted to be involved in several processes, including establishment or maintenance of epithelial cell apical/basal polarity; protein localization to synapse; and receptor clustering. Predicted to act upstream of or within establishment of planar polarity. Located in several cellular components, including dendritic shaft; growth cone; and postsynaptic density. Is active in glutamatergic synapse and postsynaptic density, intracellular component. Human ortholog(s) of this gene implicated in non-syndromic X-linked intellectual disability 90. Orthologous to human DLG3 (discs large MAGUK scaffold protein 3). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
