In eukaryotes, mRNA is recruited to the 43S pre-initiation complex (43S PIC), which consists of the 40S ribosomal subunit, translation initiation factors eIF1, eIF1A, eIF3, eIF5, and a ternary complex (TC) composed of eIF2, GTP and Met-tRNAiMet. 43S PIC binds to the 5′ end of the mRNA and scans along the 5′ untranslated region (5′UTR) in the 3′ direction to find the start codon (AUG) within the context of an optimal Kozak sequence. Start codon recognition stabilizes the 48S initiation complex (48S IC), initiates dissociation of eIF1, eIF1A, eIF2 and eIF5, and promotes recruitment of the 60S ribosomal subunit to form 80S IC ready to enter the elongation cycle of protein synthesis. |

In the initial binding state, referred to as A/T state, this aa-tRNA is in a ternary complex with the GTPase EF-Tu (eEF1A in eukaryotes) and GTP. When a Watson–Crick codon–anticodon match is recognized by the ribosome, a signal is transmitted to EF-Tu that triggers GTP hydrolysis and thereby causes the dissociation of EF-Tu from the ribosome. The subsequent accommodation of the 3′ acceptor arm of the tRNA in the PTC of the large subunit leads to a rapid peptide bond transfer |

The essential ATP-binding cassette protein ABCE1 splits 80S ribosomes into 60S and 40S subunits after canonical termination or quality-control-based mRNA surveillance processes. Compared to the pre-splitting state, we observe repositioning of ABCE1's iron-sulfur cluster domain, which rotates 150° into a binding pocket on the 40S subunit. This repositioning explains a newly observed anti-association activity of ABCE1. Notably, the movement implies a collision with A-site factors, thus explaining the splitting mechanism. |

In mammalian cells, peptide chain elongation requires two main elongation factors, eEF1A and eEF2. The latter mediates the translocation step of elongation in which the ribosome moves by the equivalent of one codon relative to the mRNA, and the peptidyl-tRNA shifts from the A- into the P-site on the ribosomend eEF2. |

The work cycle during which a new amino acid is added to the growing polypeptide chain, referred to as elongation cycle, is a repetitive multistep process encompassing aminoacyl-tRNA (aa-tRNA) selection, peptide bond formation, and mRNA–tRNA translocation (Fig. 1). In the initial binding state, referred to as A/T state, this aa-tRNA is in a ternary complex with the GTPase EF-Tu (eEF1A in eukaryotes) and GTP. When a Watson–Crick codon–anticodon match is recognized by the ribosome, a signal is transmitted to EF-Tu that triggers GTP hydrolysis and thereby causes the dissociation of EF-Tu from the ribosome.

The chaperones MPP11 and Hsp70L1 form the mammalian ribosome-associated complex. Here, we report that MPP11 is localized to the cytosol and associates with ribosomes. Purification of MPP11 revealed that it forms a stable complex with Hsp70L1, a distantly related homolog of Ssz1p. |
