The lifetime of an intracellular signaling molecule must be short for the cell to be able to cause a change in the concentration of the signaling molecule in an efficient manner. PKA is more closely related to PKC than to PKG at the amino acid level. Components of intracellular signaling pathways can be small molecules, proteins or lipids. Second messengers can convey a signal via a change in their steady state level. Negative feedback systems play important roles in regulating cellular signaling.
