Détails sur EIF4E

Antigène: EIF4E (Eukaryotic Translation Initiation Factor 4E (EIF4E))

Autre désignation: eIF4E

Sujet:

Synonyms: CBP, EIF4F, AUTS19, EIF4E1, EIF4EL1, Eukaryotic translation initiation factor 4E, eIF-4E, eIF4E, eIF-4F 25 kDa subunit, mRNA cap-binding protein

Background: Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures. Component of the CYFIP1-EIF4E-FMR1 complex which binds to the mRNA cap and mediates translational repression. In the CYFIP1-EIF4E-FMR1 complex this subunit mediates the binding to the mRNA cap.
