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]
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 been shown to interact with:
The interaction with PSD95 and S-SCAM is mediated by the GUK domain[ 13]
