What is Glutamate receptor-interacting protein?

Glutamate receptor-interacting protein refers to either a family of proteins that bind to the glutamate receptor or specifically to the GRIP1 protein within this family. Proteins in the glutamate receptor-interacting protein family have been shown to interact with GluR2, a common subunit in the AMPA receptor. This subunit also interacts with other proteins such as protein interacting with C-kinase1 and N-ethylmaleimide-sensitive fusion protein. Studies have begun to elucidate its function; however, much is still to be learned about these proteins.
