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. Plays a role in
CC       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}.
