| Hazard Information | Back Directory | [Description]
In eukaryotes, a set of initiation factors (eIFs) interact with ribosomal subunits to initiate mRNA translation. A major step in initiation is the assembly of a large multiprotein complex that includes the cap-binding protein eIF4E and the multidomain adaptor protein eIF4G. 4EGI-1 is an inhibitor of the initiation of translation that blocks the interaction of eIF4G with eIF4E (KD = 25 μM). It directly binds eIF4E, competitively inhibiting an association with eIF4G that is necessary for cap-dependent translation. 4EGI-1 prevents the expression of oncogenic proteins in mammalian cancer cells, leading to apoptosis. Research with this inhibitor supports a role for normal eIF4E/eIF4G interaction in memory consolidation and excess interaction in autism spectrum disorders. 4EGI-1 also blocks translation in some viruses that do not require eIF4E or a cap structure for initiation. | [Uses]
Selective and cell permeable inhibitor of the interaction between the human eukaryotic translation initiation factors 4E (eIF4E) and 4G (eIF4G). | [Definition]
