Scientific background

DLGAP1/GKAP (discs large homolog associated protein 1/guanylate kinase associated protein) is a member of the DLGAP family, scaffold proteins localized to the postsynaptic density. The protein is involved in signaling to and from glutamate receptors, it serves as a key adaptor protein of NMDA receptors, involved in learning and memory and synaptic plasticity in the central nervous system1,2.

DLGAP family comprises five conserved proteins, DLGAP1–DLGAP5. DLGAP1-DLGAP4 proteins interact directly with both DLG and SHANK through their multiple domains. DLGAP1–4 proteins are implicated in several neurological disorders including schizophrenia, autism, obsessive compulsive disorder and cerebellar ataxia1.

DLGAP1 is highly expressed in the brain; Dlgap1 mRNA is detected in the cortex, hippocampus, olfactory bulb, striatum and thalamus1.
