Degradation of Hypomodified tRNA\u3csub\u3ei\u3c/sub\u3e\u3csup\u3eMet\u3c/sup\u3e in vivo Involves RNA-dependent ATPase Activity of the DExH Helicase Mtr4p [PDF]

, 2008
Effective turnover of many incorrectly processed RNAs in yeast, including hypomodified tRNAi Met, requires the TRAMP complex, which appends a short poly(A) tail to RNA designated for decay. The poly(A) tail stimulates degradation by the exosome.
