GRASP1: Lysates

PDZ domain-containing proteins, such as PSD-95 and GRIP are thought to play key roles in glutamate receptor plasticity. GRIP-associated proteins (GRASPs) that bind to distinct PDZ domains within GRIP also play key roles in the regulation of glutamate receptor function. GRASP-1 is a neuronal rasGEF associated with GRIP and AMPA receptors in vivo. Studies suggest that GRASP-1 may regulate neuronal Ras signaling and contribute to the regulation of AMPA receptor distribution by NMDA receptor activity.
