This entry represents the N-terminal domain of the Impact proteins. The Impact protein is a translational regulator that ensures constant high levels of translation under amino acid starvation. It acts by interacting with Gcn1/Gcn1L1, thereby preventing activation of Gcn2 protein kinases (EIF2AK1 to 4) and subsequent down-regulation of protein synthesis [2,3]. It is evolutionary conserved from eukaryotes to archaea [1].
Members of this family pertain to a set of functionally uncharacterised hypothetical bacterial proteins. They adopt a ferredoxin-like fold, with a beta-alpha-beta-beta-alpha-beta arrangement [1].
