While ATF4 is a major downstream effector of the ISR, evidence is emerging that ATF4 can also be activated by pro-growth signals that stimulate mTORC1 signaling (Adams, 2007

However, its relative impact on overall intraepithelial cell levels of GSH, or activation of other proinflammatory mediators, is unclear and requires further study

Figure 2. Retained His-tagged protein binding capacity in presence of EDTA. Ni-Penta 6FF resins were added to 20 volumes of E.coli lysate (~0.5 mg/mL containing a His-tagged protein of 26 kDa in size), in the presence of 2 mM, 5 mM, 10 mM EDTA respectively. Protein binding was then performed at room temperature for 2 hours. After washing 5 times with 20mM sodium phosphate, 0.5 M NaCl, 5 mM imidazole, pH7.4, the target His-tagged protein was eluted with 20mM sodium phosphate, 0.5 M NaCl, 250 mM imidazole, pH7.4. Protein concentration was measured by UV absorbance at OD280

Thus, GSTs might have a dynamic interaction with other glutathione dependent enzymes to regulate cellular normal physiology
