Formation of a GDP-gamma alpha subunit complex (gamma alpha GDP)
A) follows phosphorylation of the gamma subunit.
B) increases association with target proteins.
C) is stimulated by hydrolysis-resistant analogs of GTP.
D) precedes assembly of the gamma heterotrimer.
E) requires hydrolysis of ATP.

Question

Quizplus · Accepted Answer

The formation of a GDP-gamma alpha subunit complex (gamma alpha GDP) precedes assembly of the gamma heterotrimer, meaning that the gamma alpha GDP complex is formed before the gamma subunit is assembled with the beta and alpha subunits. None of the other answer choices are directly related to the formation of the gamma alpha GDP complex.
