Immunohistochemical localization of the INsP4 receptor GTPase-activating protein GAP1IP4BP in the rat brain.


The distribution of GAP1(IP4BP), a GTPase-activating protein showing high affinity and stereospecificity for inositol 1,3,4,5-tetrakisphosphate (InsP4), was investigated by Western blot and immunohistochemistry of rodent brain with polyclonal antibodies generated against the carboxy-terminus of the cloned protein. GAP1(IP4BP)-like immunoreactivity was found… (More)
