And once GTP binds, that activates that G protein we call Ras. And once Ras is activated, it moves on and activates a protein kinase we call Raff. And once this protein kinase is activated, it goes on to form these to activate other protein kinases we call mex the Max. Once activated, it goes on to activate other protein kinases we call Hercs. Now these Hercs can actually move into the nucleus of our cell. So we have this double phospholipid bilayer of the nucleus.
