GRAP1, also designated GRASP-1 or GRIP-associated protein, contains a rasGEF (ras GDP/GTP exchange factor) domain, a caspase-3 cleavage site, a region homologous to RBD (ras binding domain) and a PDZ domain. The caspase-3 cleavage site separates these domains into an amino terminal GEF catalytic domain and a carboxyl-terminal regulatory domain, which is a proteolytic fragment. This overall structure is similar to ralGDS. GRAP1 is a member of the rasGEF (Ras protein GDP/GTP exchange factors) family. GRAP1 is expressed in the cytosol and partially localized to the membrane in all tissues of the nervous system, while the fragment is located only in the cytosol. GRAP1 associates with the seventh GRIP-1 (glutamate receptor interacting protein) PDZ domain. GRIP-1 binds to the C termini of AMPA receptors and may be an adapter protein that links AMPA receptors to other proteins. GRAP1 may be involved in the regulation of ras signaling and AMPA receptor distribution, through the activation of NMDA receptors. Caspase-3 may disrupt the proper regulation or targeting of GEF by cleaving the regulatory domain from the catalytic domain.
