Translation initiation factor 4E (eIF4E) binds the 7-methylguanosine cap st
ructure of mRNA and mediates recruitment of mRNA to ribosomes, with the pot
ential of regulating the overall rate of translation and discriminating bet
ween different RNAs. Increased translation is required for progress through
the cell cycle, and it is therefore not surprising that eIF4E has oncogeni
c Properties when overexpressed. The function of this review is to summaris
e what is known about eIF4E gene and protein structure, biological function
and medical relevance. (C) 1999 Elsevier Science Ltd. All rights reserved.
