GRASP55 (Golgi re-assembly stacking protein of 55 kDa) and GRASP65 (a 65 kDa) protein are highly homologous. GRASP55 is a component of the Golgi stacking machinery. GRASP65, an N-ethylmaleimide- sensitive membrane protein required for the stacking of Golgi cisternae in a cell-free system [1]. This region appears to be related to the PDZ domain.	Domain
