... level only after 60 min (Fig. 1). Pyp1p and Pyp2p phosphatases appear to play a key role in the dephosphorylation of the osmotic stress-activated Sty1p [20]. Interestingly, however, the Sty1p activation ... shock induced a quick and transient phosphorylation of Sty1p that became dephosphorylated within 60–90 min. This is likely due to the activity of threonine-phosphatases...
