Research Abstract |
Recently, we have identified BRINP family genes encoding three novel proteins that are specifically expressed in the nervous system and possess an ability to suppress cell cycle transition. In the present study, to gain insight into the physiological roles of BRINP family proteins, we raised and analyzed BRINP1-knockout mice. As a result, we found BRINP1 is induced remarkably in dentate gyrus in an activity dependent manner, and rescue hippocampal CA3 neurons from excitotoxic degeneration. Moreover, BRINP1-knockout mice showed specific behaviors such as hyper locomotive activity, lack of endurance and sociality that resembles some forms of psychiatric disorder.
