Abstract

Lysine acetylation/deacetylation is increasingly being recognized as common post-translational modification that appears to be broadly operational throughout the cell. The functional roles of these modifications, outside of the nucleus, have not been extensively studied. Moreover, as acetyl-CoA donates the acetyl group for acetylation, nutrient availability and energetic status may be pivotal in this modification. Similarly, nutrient limitation is associated with the deacetylation reaction. This modification is orchestrated by a novel family of sirtuin deacetylases that function in a nutrient and redox dependent manner and targets non-histone protein deacetylation. In compartment-specific locations, candidate target proteins undergoing lysine-residue deacetylation are being identified. Through these investigations, the functional role of this post-translational modification is being delineated. We review the sirtuin family proteins, discuss their functional effects on target proteins, and postulate on potential biological programs and disease processes that may be modified by sirtuin-mediated deacetylation of target proteins.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The SIR2 family of histone deacetylases deacetylates both histones and nonhistone proteins and thus modulates multiple cellular functions and affects gene expression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
