Rabbit polyclonal antibody to eIF3ζ (R135)

Translation initiation in eukaryotes necessitates the assembly of an 80S ribosomal complex containing methionyl initiator tRNA (Met~tRNAiMet), which is base paired at the initiation codon (AUG, GUG) in eligible transcripts. Eukaryotic initiation factors (eIFs) are utilized in a sequence of reactions that leads to 80S ribosomal assembly and initiation of translation. Eukaryotic initiation factor 3 (eIF3) is the largest family of eIFs and consists of at least 12 unique subunits in mammals. eIFε, also known as eIF p47, binds to the 40S ribosome and promotes the binding of methionyl~tRNAi and mRNA and associates with the complex p170~eIF3.
