MeSH Heading: Eukaryotic Initiation Factor-1
Tree Number(s): D12.776.835.725.868.124
Unique ID: D015977
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D015977
Scope Note: 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.
Entry Term(s): EIF-1; Eukaryotic Peptide Initiation Factor-1; Peptide Initiation Factor EIF-1
