Web16 feb. 2016 · Increased phosphorylation of eIF2α can result from the action of eIF2α kinases—general control nondepressible 2 (GCN2), heme-regulated inhibitor (HRI), RNA-dependent protein kinase (PKR) and PKR-like ER-resident protein kinase (PERK), or from the inhibition of the eIF2α phosphatase serine/threonine protein phosphatase 1 (PP1) ( … Web1 dec. 2024 · Here, we found that a multikinase inhibitor, GZD824, which we identified using a cell-based assay with ATF4 immunostaining, inhibited the GCN2 pathway in cancer cells. Indeed, GZD824 suppressed GCN2 activation, eIF2 α phosphorylation, and ATF4 induction during amino acid starvation stress.
