| Annotation description: | Figure 6: confocal imaging of immunofluorescence labeling for Mind Bomb-2 (MIB2) and PSD-95 (DLG4) in cultured rat hippocampal neurons showed partial co-localization. Figure 7: Mib2 associates with the NR2B subunit in the hippocampus. "forskolin treatment resulted in an increase in NR2B phosphorylation (lanes 1 versus 2, top panel), and a corresponding increase in Mib2 co-immunoprecipitation with the NR2B subunit (lanes 1 versus 2, bottom panel). Similar results were obtained when KCl was added at the last 5 min of forskolin treatment to mimic brief neuronal stimulation (Fig. 7, lanes 3 versus 1 and 2). Together these results suggest that in the hippocampus, Mib2 binds NR2B in an activity-dependent manner." |
