c-Src activates endonuclease-mediated mRNA decay.

The mRNA endonuclease PMR1 initiates mRNA decay by forming a selective complex with its translating substrate mRNA. Previous work showed that the ability of PMR1 to target to polysomes and activate decay depends on the phosphorylation of a tyrosine residue at position 650. The current study shows that c-Src is responsible for activating this mRNA decay… (More)
