abstract = {The translation of mRNA into proteins in multicellular
organisms needs to be carefully tuned to changing proteome
demands in development and differentiation, while defects in
translation often have a disproportionate impact in distinct
cell types. Here we used inducible CRISPR interference
screens to compare the essentiality of genes with functions
in mRNA translation in human induced pluripotent stem cells
(hiPS cells) and hiPS cell-derived neural and cardiac cells.
We find that core components of the mRNA translation
machinery are broadly essential but the consequences of
perturbing translation-coupled quality control factors are
cell type dependent. Human stem cells critically depend on
pathways that detect and rescue slow or stalled ribosomes
and on the E3 ligase ZNF598 to resolve a distinct type of
ribosome collision at translation start sites on endogenous
mRNAs with highly efficient initiation. Our findings
underscore the importance of cell identity for deciphering
the molecular mechanisms of translational control in
metazoans.},
