RT "A novel translational repressor mRNA is edited extensively in livers
RT containing tumors caused by the transgene expression of the apoB mRNA-
RT editing enzyme.";
RL Genes Dev. 11:321-333(1997).
CC -!- FUNCTION: Appears to play a role in the switch from cap-dependent to
CC IRES-mediated translation during mitosis, apoptosis and viral
CC infection. Cleaved by some caspases and viral proteases.
CC {ECO:0000250|UniProtKB:P78344, ECO:0000269|PubMed:9030685}.
CC -!- SUBUNIT: Interacts with the serine/threonine protein kinases MKNK1 and
CC MKNK2. Binds EIF4A and EIF3. Interacts with MIF4GD (By similarity).
CC {ECO:0000250}.
CC -!- PTM: Phosphorylation; hyperphosphorylated during mitosis.
CC {ECO:0000250|UniProtKB:P78344}.
CC -!- MISCELLANEOUS: This gene has been shown to be extensively edited in the
CC liver of APOBEC1 transgenic animals. Its aberrant editing could
CC contribute to the potent oncogenesis induced by overexpression of
CC APOBEC1. The aberrant edited sequence, called NAT1, is likely to be a
CC fundamental translational repressor.
CC -!- SIMILARITY: Belongs to the eukaryotic initiation factor 4G family.
CC {ECO:0000305}.
