DLG2

Disks large homolog 2 (DLG2) also known as channel-associated protein of synapse-110 (chapsyn-110) or postsynaptic density protein 93 (PSD-93) is a protein that in humans is encoded by the DLG2 gene.

Function
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.

Interactions
DLG2 has been shown to interact with GRIN2B, KCNJ12.
