Analysis of the c-myc IRES; a potential role for cell-type specific trans-acting factors and the nuclear compartment

Abstract excerpt

The 5' UTR of c -myc mRNA contains an internal ribo-some entry segment (IRES) and consequently, c -myc mRNAs can be translated by the alternative mechanism of internal ribosome entry. However, there is also some evidence suggesting that c -myc mRNA translation can occur via the conventional cap-dependent scanning mechanism. Using both bicistronic and monocistronic mRNAs containing the c- myc 5' UTR, we...
