In the present study, we investigated the effects of pentylenetetrazol (PTZ), a chemical convulsant that interacts with the GABA A receptor, in mice lacking the phospholipase C (PLC)-related inactive protein-1 (PRIP-1). PRIP-1 knockout mice did not develop spontaneous behavioral seizure. PRIP-1 knockout mice had markedly shorter latencies until the first clonic convulsion (CL) and tonic extensor (TE) following PTZ administration and increased incidence of convulsion compared to those in wild-type mice. Furthermore, the mortality rate by PTZ in mice lacking the PRIP-1 was also significantly increased in comparison with that in wild-type mice. These findings suggested that mice lacking the PRIP-1 were hypersensitive to PTZ-induced convulsion, and PRIP-1 might play roles in suppressing excessive excitability via interactions with the GABA A receptor.
