Mechanism of RNA polymerase III termination-associated reinitiation-recycling conferred by the essential function of the N terminal-and-linker domain of the C11 subunit

RNA polymerase III (Pol III) employs termination-associated reinitiation-recycling to express high amounts of tRNAs, which involves the essential C11 subunit. Here the authors determine the functions of various C11 domains, finding that the N-terminal domain (NTD) stimulates termination, reinitiatio...

Sumario:RNA polymerase III (Pol III) employs termination-associated reinitiation-recycling to express high amounts of tRNAs, which involves the essential C11 subunit. Here the authors determine the functions of various C11 domains, finding that the N-terminal domain (NTD) stimulates termination, reinitiation-recycling requires an NTD-linker, and the C-terminal domain stimulates RNA 3′-cleavage.
