Exosome substrate targeting: the long and short of it.


The exosome ribonuclease complex functions in both the limited trimming of the 3'-ends of nuclear substrates during RNA processing events and the complete destruction of nuclear and cytoplasmic RNAs. The two RNases of the eukaryotic exosome, Rrp44 (rRNA-processing protein 44) and Rrp6, are bound at either end of a catalytically inert cylindrical core. RNA… (More)
