Eif1 function
WebJan 11, 2008 · Eukaryotic initiation factor (eIF) 1 is a small protein (12 kDa) governing fidelity in translation initiation. It is recruited to the 40 S subunit in a multifactor complex with Met-tRNA(i)(Met), eIF2, eIF3, and eIF5 and binds near the P-site. eIF1 release in response to start codon recognition is an important signal to produce an 80 S initiation complex.

WebInitiation factor eIF1 promotes binding of initiator tRNA, in the form of a ternary complex of eIF2–GTP–Met–tRNA iMet, to preinitiation complexes of the SSU. It also serves to prevent initiation at non–start codons, likely by promoting an “open” state of the SSU ( Jackson et al. 2010; Hinnebusch 2011 ). WebWe have examined the role of the mammalian initiation factor eIF1 in the formation of the 40 S preinitiation complex using in vitro binding of initiator Met-tRNA (as Met-tRNA (i).eIF2.GTP ternary...
WebeIF1, eIF1A, and eIF2 directly interact with the 40S subunit, the eukaryotic ribosomal small subunit (SSU), prevent the SSU reassociation with the large subunit, and load Met-tRNAMetionto the P-site (Translation Initiation). The direct partner of Met-tRNAMetiis eIF2 made of α, β, and γ subunits. WebeIF1 is a conserved translation protein in all eukaryotic cells that is responsible for the investigation of codon-anticodon mismatches during the initiation of translation. In order …
