Abstract excerpt

The dinucleotide AppppA (5',5'''-P1, P4-diadenosine tetraphosphate) is rapidly synthesized in cells exposed to heat stress or oxidative stress. Stress-induced AppppA accumulation has been observed in all cell types studied to date. In order to study the function(s) of AppppA, we created a mutatio...
