A GCN1-independent activator of the kinase GCN2
Mutations of EIF2AK4 , which encodes the eIF2α kinase GCN2, cause a severe inherited form of pulmonary hypertension called pulmonary veno-occlusive disease (PVOD). Some pathogenic variants of GCN2 are amenable to pharmacological reactivation by low concentrations of ATP pocket-binding inhibitors. Kinase inhibition at modestly elevated concentrations limits the clinical utility of these drugs…
