| Research Abstract |
We have studied about the roles of GRIN family, which binds to Gαi/o subunits, in the brain. In this study, we were able to generate both conditional GRIN1 KO mice and simple GRIN3 KO mice. Also, GRIN1 knockdown by lentivirus based RNAi system was successful. GRIN1 knockdown in retinoic acids induced neuronal P19 cells caused the reduction of GABAB2 receptor without the affect of Gαo expression. Furthermore, stimulation of cannabinoid receptor 1 (CB1) agonist could not activate the ERK pathway in these cells. On the other hand, ablation of GRIN3 in mice led to the decrease of both dopamine D1 and D2 receptors. These observations indicate that GRIN family plays the roles for GPCR function, such as stability and turn ov er in the cell membranes.
