In Trimeric G Proteins Gtp Binds to?

Question: In trimeric G-proteins, GTP binds to the alpha subunit.

How does GTP bind to G-protein?

When GTP is bound to the G-protein, the α subunit dissociates from the βγ complex and activates the G-protein. Following activation, both the GTP-bound α subunit and the free βγ complex can bind to downstream effector molecules and mediate a variety of responses in the target cell.

What do GTP-binding proteins do?

GTP-binding proteins or G proteins are transmitting signals outside the cell which cause changes within the cell. They act as molecular switches which are on when binding GTP and off when binding GDP.
