CC   -!- FUNCTION: Translational regulator that ensures constant high levels of
CC       translation upon a variety of stress conditions, such as amino acid
CC       starvation, UV-C irradiation, proteasome inhibitor treatment and
CC       glucose deprivation. Plays a role as a negative regulator of the
CC       EIF2AK4/GCN2 kinase activity; impairs GCN1-mediated EIF2AK4/GCN2
CC       activation, and hence EIF2AK4/GCN2-mediated eIF-2-alpha phosphorylation
CC       and subsequent down-regulation of protein synthesis. May be required to
CC       regulate translation in specific neuronal cells under amino acid
CC       starvation conditions by preventing GCN2 activation and therefore ATF4
CC       synthesis. Through its inhibitory action on EIF2AK4/GCN2, plays a role
CC       in differentiation of neuronal cells by stimulating neurite outgrowth.
CC       {ECO:0000250|UniProtKB:O55091}.
CC   -!- SUBUNIT: Interacts with GCN1; prevents the interaction of GCN1 with
CC       EIF2AK4/GCN2 and inhibits EIF2AK4/GCN2 kinase activity. Interaction
CC       with RPL39; this interaction occurs in a GCN1-independent manner.
CC       Associates with ribosomes; this interaction occurs in a GCN1-
CC       independent manner. Associates with actin; this interaction occurs in a
CC       GCN1-independent manner. {ECO:0000250|UniProtKB:O55091}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:O55091}.
CC   -!- SIMILARITY: Belongs to the IMPACT family. {ECO:0000305}.
