Guanosine Triphosphate 56-59 guanine nucleotide binding protein, alpha O Mus musculus 133-141 2494307-1 1989 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 major brain G protein. Guanosine Triphosphate 16-19 guanine nucleotide binding protein, alpha O Mus musculus 341-349
