StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionseIF-4E Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name EIF4E
Synonyms EIF4EL1, EIF4F
Function 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.
Cellular Location Cytoplasm, P-body. Cytoplasm

eIF-4E is a eukaryotic translation initiation factor involved in directing ribosomes to the cap structure of mRNAs. It exists in two forms: as a free form (25 kDa) and as part of a multiprotein complex eIF-4F (1). eIF-4E appears to be the least abundant of the initiation factors and acts as a rate-limiting step of initiation (2). Since translation is regulated by phosphorylation, eIF-4E phosphorylation at Ser 209 by MAPK signal-integrating kinase 1 (Mnk1) and kinase 2 (Mnk2) may directly regulate the rate of protein synthesis initiation (3). There is also evidence that eIF-4E can function as an oncogene (4-5).
