Anti-sigma factors
Open accessAbstract
Anti-sigma factors modulate the expression of numerous regulons controlled by alternative sigma factors. Anti-sigma factors are themselves regulated by either secretion from the cell (i.e. FlgM export through the hook-basal body), sequestration by an anti-anti-sigma (i.e. phosphorylation regulated partner-switching modules), or interaction with extracytoplasmic proteins or small molecule effectors (i.e. transmembrane regulators of extracytoplasmic function sigma factors). Recent highlights include the genetic description of the opposed sigma/anti-sigma binding surfaces; the unexpected role of FlgM in holoenzyme destabilization and the finding that folding of FlgM is coupled to sigma28 binding; the first structure determination for an anti-sigma antagonist; and the detailed dissection of two complex partner-switching modules in Bacillus subtilis.

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.
