| initiation factor a/eIF2(gamma) | binding of translation initiation factor a/eIF2(gamma) to the 5'-end of mRNA counteracts the 5'-to-3' exoribonucleolytic activity in vitro. The factor binds by virtue of the gamma-subunit to the 5'-end of tri-phosphorylated mRNAs and thereby increases the stability of the 5'-part of mRNAs | Saccharolobus solfataricus |
