| Product description |
GRASP (GRP1-associated scaffold protein, tamalin) is a 395 amino acid proteinencoded by the human gene GRASP . GRASP is a scaffold protein that com-prises multiple protein-interacting domains, including a 95 kDa postsynapticdensity protein (PSD-95)/discs-large/ZO-1 (PDZ) domain, a leucine-zipperregion and a carboxyl-terminal PDZ-binding motif. GRASP is involved withintracellular trafficking and contributes to the macromolecular organizationof group 1 metabotropic glutamate receptors (mGluRs) at synapses. GRASPforms a heteromer composed of GRASP , PSCD2 and at least one mGluR-1. Italso interacts with PSCD3, mGluR-2, mGluR-3 and mGluR-5. GRASP is highlyexpressed in brain and has lower levels of expression in lung, heart, embryo, kidney and ovary.1) Kitano, J., Kimura, K., Yamazaki, Y., Soda, T., Shigemoto, R., Nakajima, Y. and Nakanishi, S. 2002.
