| description | Members of the golgin subfamily A were identified as Golgi auto-antigens []. They might be involved in maintaining cis-Golgi structure []. One of the members of this family, member 2 or GM130, is a specific interacting partner of the small GTPase Rab1b []and plays a key role in the disassembly and reassembly of the Golgi apparatus during mitosis. GM130 is also involved in vesicle tethering and fusion at the cis-cisternae to facilitate transit between transport vesicles and the stacked cisternae. It interacts with GRASPs proteins, which mediate the stacking of Golgi cisternae []. Additionally, GM130 was localised to the spindle poles and regulates microtubule organization [].Structurally, GM130 is comprised of six coiled-coil regions in the middle, a Golgi-targeting domain at the C terminus, and a p115-interacting motif at the N terminus []. This entry represents the C-terminal motif of the golgin subfamily A member 2 protein (or GM130) that is bound by the GRASP65 PDZ1 and PDZ2 domains [, ]. These interactions are required for their association and localisation of GRASP65 to the cis-cisternae. |
