WebbEukaryotic initiation factors ( eIFs) are proteins or protein complexes involved in the initiation phase of eukaryotic translation. These proteins help stabilize the formation of ribosomal preinitiation complexes around the start codon and are an important input for post-transcription gene regulation. Webbin·i·ti·a·tion. 1. The first stage of tumor induction by a carcinogen; subtle alteration of cells by exposure to a carcinogenic agent so that they are likely to form a tumor on subsequent exposure to a promoting agent (that is, promotion). 2.

WebbHowever, initiation of transcription is much more complex in eukaryotes compared to prokaryotes. Unlike the prokaryotic RNA polymerase that can bind to a DNA template on its own, eukaryotes require several other proteins, called transcription factors , to first bind to the promoter region and then help recruit the appropriate polymerase.
