Proteins with RNA Chaperone Activity: A World of Diverse Proteins with a Common Task—Impediment of RNA Misfolding

Figure 3

Hypothetical mechanisms of RNA chaperoning. (a) shows folding of an RNA molecule in the presence of RNA chaperones (blue). RNA chaperones and proteins with RNA chaperone activity prevent the RNA from misfolding and increase annealing of the correct structure by crowding. (b) Proteins with RNA chaperone activity possessing disordered regions (blue) interact with misfolded RNA. Upon energy transfer, the RNA structure loosens and the disordered protein domain becomes more ordered. Proteins with RNA chaperone activity are dispensable in both cases after the RNA has folded into its native form.
