Analyses of yeast codon usage and ribosome profiling data reveal a nonoptimal codon cluster in the mRNAs of ER-targeted proteins, downstream of the SRP-binding site, that would slow down translation to promote SRP interaction.
A systematic analysis reveals features of proteins synthesized at distal locations owing to mRNA localization, including the presence of intrinsically disordered segments and assembly-promoting modules. These findings suggest that asymmetric protein distribution enhances interaction fidelity.
