P400 protein is a 250 kd glycoprotein, characteristic of the cerebellum, which is accumulated at the endoplasmic reticulum, at the plasma membrane and at the post-synaptic density of Purkinje cells. In this study, we purified inositol 1,4,5-trisphosphate (InsP3) receptor from mouse cerebellum and examined the possibility that P400 protein is identical with cerebellar InsP3 receptor protein. InsP3 receptor was solubilized with Triton X-100 from a post-nuclear fraction of ddY mouse cerebellum and… CONTINUE READING
