Ribosome-quality control antagonizes the activation of integrated-stress response on colliding ribosomes

Ribosome stalling occurring on aberrant mRNA activates quality control pathways to maintain proteostasis. Recently, ribosome stalling has also been linked to the activation of Gcn2 and the subsequent integrated-stress response (ISR). How the two processes are coordinated is not completely clear. Here we show that activation of ribosome-quality control by Hel2 suppresses that of Gcn2 in yeast. In the absence of Hel2, we observe a gene-expression signature indicative of ISR activation, suggesting...

Provenance — who produced it, who reused it

Linked to 1 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.

Standardized, field-standard QC computed by touching the data — every metric states how it was obtained

No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.

measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently
