Translation initiation is the process by which the ribosome and its associated factors bind to an mRNA and are assembled at the start codon. This process is defined as either cap-dependent, in which the ribosome binds initially at the 5' cap and then travels to the stop codon, or as cap-independent, where the ribosome does not initially bind the 5' cap. Webb26 nov. 2024 · The most prominent one is the cap-dependent ribosomal scanning, which occurs during translation initiation and involves loading of the 40S ribosomal subunit near the 5′-end of mRNA (that usually contains the m 7 G-cap) and its directional movement towards the 3′-end until the start codon [ 1, 5 ]. 姿形しけいWebb20 jan. 2000 · The resulting complex requires eIF1, eIF1A, eIF4A, eIF4B and eIF4F to bind to a messenger RNA and to scan to the initiation codon2. eIF5 stimulates hydrolysis of … b to b とはメリット

"Eukaryotic 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. Several initiation factors form a complex with the small 40S ribosomal subunit and Met-tRNAi called the 43S preinitiation complex (43S PIC). Additional factors of the eIF4F complex (eIF4A, E, a… " - Ribosomal initiation complex
