Eukaryot initieringsfaktor som binder till ribosomala 40s-underenheter. Den kallas eIF-1 hos eukaryoter och IF-1 hos bakterier, och ansågs ursprungligen som en icke-essentiell faktor vid eukaryot transkriptionsinitiering. Men den anses numera spela en viktig roll för lokalisering av ribosomer i mRNA's initieringskodon. Syn. eukaryot initieringsfaktor 1.
A eukaryotic initiation factor that binds to 40S ribosomal subunits. Although initially considered a "non-essential" factor for eukaryotic transcription initiation, eukaryotic initiation factor-1 is now thought to play an important role in localizing RIBOSOMES at the initiation codon of MRNA.
