Apical localization of the alpha subunit of GTP-binding protein Go in choroidal and ciliated ependymocytes.


The presence of GTP-binding proteins (G proteins) has been studied in murine adult choroid plexuses and cultured fetal choroidal or hypothalamic ependymal cells by ADP-ribosylation catalyzed by Bordetella pertussis toxin (PTX) and by immunodetection using affinity-purified polyclonal antibodies against the alpha subunit of the Go protein (Go alpha), the… (More)
