GRASP encodes a protein that functions as a molecular scaffold, linking receptors, including group 1 metabotropic glutamate receptors, to neuronal proteins. The encoded protein contains conserved domains, including a leucine zipper sequence, PDZ domain and a C-terminal PDZ-binding motif. Alternately spliced transcript variants have been observed for GRASP .GRASP (General Receptor For Phosphoinositides 1 Associated Scaffold Protein) is a Protein Coding gene.
