[5][6] Chapsyn-110/PSD-93 a member of the membrane-associated guanylate kinase (MAGUK) family.

The protein forms a heterodimer with a related family member that may interact at postsynaptic sites to form a multimeric scaffold for the clustering of receptors, ion channels, and associated signaling proteins.

Alternatively spliced transcript variants encoding distinct isoforms have been described but their full-length nature has yet to be completely determined.

[7] DLG2 has been shown to interact with GRIN2B,[8][9] KCNJ12.
