However, when a special Sec-insertion sequence (SECIS), a stem-loop structure, is present downstream (in the untranslated region in mammals), UGA is translated as Sec<ref name='21st' /><ref name='Palioura' />. This involves the interaction of this stem-loop structure with specialized elongation factors called SelB in bacteria and EFSec in humans<ref name='Palioura' />. | ||
