Bis(5'-nucleosyl)-tetraphosphatase (asymmetrical) (NUDT2) mediates the asymmetrical hydrolysis of P(1),P(4)-bis(5'-guanosyl) tetraphosphate (GP4G) to yield AMP and ATP. GP4G is implicated in the regulation of cellular responses to stress and its hydrolysis could serve as a mechanism by which homeostasis is maintained by preventing its build-up (Thorne et al. 1995, Swarbrick et al. 2005).
