Disks large-associated protein 1 (DAP-1), also known as guanylate kinase-associated protein (GKAP), is a protein that in humans is encoded by the DLGAP1 gene. DAP-1 is known to be highly enriched in synaptosomal preparations of the brain, and present in the post-synaptic density. [5]

Function

This gene encodes the protein called guanylate kinase-associated protein (GKAP). GKAP binds to the SHANK2 and PSD-95 proteins, facilitating the assembly of the post-synaptic density of neurons. [6] Dlgap1 has five 14-amino-acid repeats and three Pro-rich portions.

Interactions

DLGAP1 has been shown to interact with:

The interaction with PSD95 and S-SCAM is mediated by the GUK domain [13] and it has been hypothesized that this might mean it can also interact with other GUK containing proteins.
