Coping with stress: calmodulin and calcineurin in model and pathogenic fungi

Kraus, Peter R, Heitman, Joseph·2003·Biochemical and Biophysical Research Communications

Abstract

Calcium signaling via calmodulin and calcineurin is critical for the regulation of stress responses in fungi. The functions of calmodulin and calcineurin are largely conserved among pathogenic fungi and model fungi, however, the mechanisms of action have diverged. Saccharomyces cerevisiae is an excellent model for understanding the framework of calcium-mediated signal transduction pathways, and considerable progress has been made in understanding the details of how Ca(2+)-calmodulin and calcineurin control adaptation to environmental stress. Studies using the divergent human pathogenic fungi Candida albicans and Cryptococcus neoformans reveal that calcineurin is critical for virulence, yet it acts via distinct mechanisms in each fungus. These differences in function may reflect the requirements of each pathogen to survive inside the host, and illustrate that studies must be conducted in each organism in order to elucidate the details of the molecular mechanisms of calmodulin and calcineurin-mediated signaling pathways.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Calcineurin is a heterodimer consisting of a catalytic A subunit and a Ca2+-binding regulatory B subunit, and the association between the two subunits is necessary for phosphatase activity.

    “Calcineurin is a heterodimer consisting of a catalytic A subunit and a Ca2+-binding regulatory B subunit, and the association between the two subunits is necessary for phosphatase activity (19).”
  • In fungi, calcineurin mediates responses to environmental stress conditions that compromise cell viability.

    “The characterization of this enzyme in genetically tractable yeasts has revealed a major role for calcineurin in fungi as mediator of responses to environmental stress conditions that compromise cell viability (reviewed in Kraus and Heitman 2003;Cyert 2003;Sugiura et al. 2002).”

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.
