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 regulation of glutamate receptor function. GRASP-1 is a neuronal rasGEF associated with GRIP and AMPA receptors in vivo (Scannevin and Huganir, 2000). Recent work suggests that GRASP-1 may regulate neuronal ras signaling and contribute to the regulation of AMPA receptor distribution by NMDA receptor activity (Ye et al., 2000).1) Scannevin RH, Huganir RL (2000) Postsynaptic organization and regulation of excitatory synapses.

Immunogen
Peptide corresponding to amino acid residues from the C-terminal region of rat GRASP, conjugated to keyhole limpet hemocyanin (KLH).
Key Feature
Clonality
Polyclonal
Host Species
Rabbit
Tested Applications
WB
The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, canine, human and mouse based on the fact that these species have 100% homology with the amino acid sequence used as antigen.
