cAMP 2nd Messenger Pathway and Experiments

... cell line is obtained. The cell line is thought to not have adenylyl cyclase within it, and is called cyc-. You need to test that it doesn't have ... hormone receptor. It interacts with GTP regulatory site to prohibit the GDP from binding. If ATP or GTP were eliminated from the reaction, it would ...

G protein coupled receptor

... G-protein binds to it, and underogoes a conformational change so that GDP is exchanged for GTP. --> the receptor acts like a GEF (guanine nucleotide ... of the G-protein --> the alfa subunit can activate adenylyl cyclase for example by a conformational change so that adenylyl cyclase produces ...
