=== ===
Glutamate Receptor Interacting Protein 1 is a protein encoded by the GRIP1 gene. It belongs to the PDZ domain proteins and is primarily localized to Postsynaptic membranes.
GRIP1 is a 150 kDa protein with multiple domains that enable its scaffolding and signaling functions in neurons.
AMPA receptor scaffolding, synaptic plasticity, receptor trafficking. This protein plays important roles in maintaining normal neuronal function and synaptic transmission.
Alterations in GRIP1 have been associated with several neurodegenerative and neurological disorders. Studies have shown changes in expression and mutations in various disease contexts.
Research is ongoing to develop therapeutic approaches targeting GRIP1 for neurological disorders.

GRIP1 (Glutamate Receptor Interacting Protein 1) functions as a critical scaffold protein at excitatory synapses. It contains seven PDZ domains that mediate protein-protein interactions with various targets:
| PDZ Domain | Binding Partners | Function |
|---|---|---|
| PDZ1-2 | GluA2/3 | AMPA receptor anchoring |
| PDZ3-4 | IRSp53/MIM | Actin linkage |
| PDZ5-6 | Various kinases | Signaling scaffolds |
| PDZ7 | Neurexin | Trans-synaptic interactions |
GRIP1 exhibits high expression in:
This widespread cortical expression underlies its importance in learning, memory, and motor control.
Targeting GRIP1 interactions offers therapeutic potential:
