G-Protein Coupled Vs. Protein Kinase Flashcards
1
Q
G protein - coupled
A
When a ligand (signal) attaches to the receptor, GTP replaces GDP on the alpha subunit, then affecting the effector protein, making GTP hydrolyzed to GDP + P
2
Q
Intracellular Receptors
A
Where: inside the cell (cytoplasm or nucleus)
Memorize: intra = inside
Ligands are small nonpolar / hydrophobic molecules that can press through the cell membrane
3
Q
Protein Kinase Signaling
A
transduce signals from the cell membrane into the interior of the cell.
