Human-Xenopus chimeras of Gsα reveal a new region important for its activation of adenylyl cyclase Antonelli, Marcelo; Birnbaumer, Lutz; Allende, Jorge E.; Olate, Juan (1994)G proteins are heterotrimeric GTPases that play a key role in signal transduction. The α subunit of Gs bound to GTP is capable of activating adenylyl cyclase. The amino acid sequences derived from two X. laevis cDNA clones ...

Olate, Juan; Jorquera, Hugo; Purcell, Patricia; Codina, Juan; Birnbaumer, Lutz; Allende, Jorge E. (1989)Xenopus laevis oocytes are cells ideally suited to the study of signal transduction and of the G-proteins that are involved in this process. A X. laevis cDNA library in λgt10 has been screened with a mixture of three ...

Birnbaumer, Lutz; Olate, Juan; Allende, Catherine C.; Allende, Jorge E.; Sekura, Ronald D. (1984)Membranes were obtained from Xenopus laevis oocytes after removal of follicular cells by collagenase treatment. [32P]ADP-ribosylation with pertussis toxin showed them to contain a single Mr = 40 000 substrate for this toxin ...
