General annotation (Comments)

Function

Appears to play a role in the switch from cap-dependent to IRES-mediated translation during mitosis, apoptosis and viral infection. Cleaved by some caspases and viral proteases. Ref.1 Ref.3 Ref.9 Ref.10

Subunit structure

Interacts with the serine/threonine protein kinases MKNK1 and MKNK2. Binds EIF4A and EIF3. Interacts with MIF4GD. Ref.1 Ref.2 Ref.8 Ref.14

Tissue specificity

Ubiquitously expressed in all adult tissues examined, with high levels in skeletal muscle and heart. Also expressed in fetal brain, lung, liver and kidney. Ref.1 Ref.3 Ref.2

Post-translational modification

Phosphorylation; hyperphosphorylated during mitosis. Ref.9 Ref.11 Ref.12 Ref.13 Ref.15 Ref.17 Ref.18

Miscellaneous

This gene has been shown to be extensively edited in the liver of APOBEC1 transgenic animal model. Its aberrant editing could contribute to the potent oncogenesis induced by overexpression of APOBEC1. The aberrant edited sequence, called NAT1, is likely to be a fundamental translational repressor.

Sequence similarities

Belongs to the eIF4G family.

Contains 1 MI domain.

Contains 1 MIF4G domain.

Contains 1 W2 domain.
