Yeast minimizes protein-expression noise preferentially for essential genes and protein-complex subunits, supporting that noise is generally harmful.

Key findings

Noise is minimized for essential genes and complex subunits via transcriptional/translational control, at a cost; noise appears generally deleterious.

Methodology

Analyzed genome-wide expression strategies in yeast to test whether genes for which noise would be most harmful show reduced stochastic expression.

Limitations

Hidden variables could bias genome-wide patterns; protein degradation’s role needs genome-wide half-life data.

Role on claims

Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.

  • SupportsGene expressionconcept

    Multiple empirical papers in this library examine gene expression with mechanistic biological findings.

    Evidence for the claim as stated.

  • SupportsGene expressionconcept

    Noise is minimized for essential genes and complex subunits via transcriptional/translational control, at a cost; noise appears generally deleterious.

    Evidence for the claim as stated.

  • SupportsGene expressionconcept

    Systems and scales differ across gene expression studies (species, tissues, methods), so mechanisms should not be over-generalised.

    Evidence for the claim as stated.
