Structure of the mammalian ribosomal pre-termination complex associated with eRF1-eRF3-GDPNP

Structural highlights

3j5y is a 4 chain structure with sequence from [1], Human and Oryctolagus cuniculus. This structure supersedes the now removed PDB entry 3j2k. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Gene:	ETF1, ERF1, RF1, SUP45L1 (HUMAN), GSPT1, ERF3A (HUMAN)

Function

[ERF1_HUMAN] Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA. Component of the transient SURF complex which recruits UPF1 to stalled ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons.^[1] [ERF3A_HUMAN] Involved in translation termination in response to the termination codons UAA, UAG and UGA. Stimulates the activity of ERF1. Involved in regulation of mammalian cell growth. Component of the transient SURF complex which recruits UPF1 to stalled ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons.

Publication Abstract from PubMed

Eukaryotic translation termination results from the complex functional interplay between two release factors, eRF1 and eRF3, in which GTP hydrolysis by eRF3 couples codon recognition with peptidyl-tRNA hydrolysis by eRF1. Here, we present a cryo-electron microscopy structure of pre-termination complexes associated with eRF1*eRF3*GDPNP at 9.7 -A resolution, which corresponds to the initial pre-GTP hydrolysis stage of factor attachment and stop codon recognition. It reveals the ribosomal positions of eRFs and provides insights into the mechanisms of stop codon recognition and triggering of eRF3's GTPase activity.
