A new mechanism of regulating RNA degradation

... "Both Upf1 and Staufen1 can be phosphorylated, so their activities could be regulated by cell signaling pathways, such as those mediated by changes in growth conditions." That would allow the cell to differentially control the level of SMD-target RNAs, while leaving the NMD-regulated RNAs untouched. This...
