The two main classes of molecular switches include changes in phosphorylation state or changes in guanine nucleotide binding. In this regard, do you think that protein kinases and guanine nucleotide exchange factors (GEFs) always turn proteins on (activate) and protein phosphatases and GTPase activating proteins (GAPs) always turn them off?

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
