Dissecting ICRAC, a store-operated calcium current

Hogan, Patrick G., Rao, Anjana·2007·Trends in Biochemical Sciences

Abstract

The use of Ca(2+) for intracellular signalling necessitates tight local and global control of cytoplasmic Ca(2+) concentration, and mechanisms for maintaining the net Ca(2+) balance. It has long been recognized that intracellular Ca(2+) stores exert control over Ca(2+) influx at the plasma membrane through a process of store-operated Ca(2+) entry (SOCE). The Ca(2+) current I(CRAC) is the best characterized instance of SOCE, but the elements of the pathway leading to I(CRAC) have eluded biochemical definition for more than a decade. However, the recent identification of key proteins underlying I(CRAC)--STIM1 and Orai1--has led to several insights into this ER-to-plasma membrane signalling system and to the recognition that it is an ancient and conserved mechanism in multicellular organisms.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

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?

  • The La3+-induced block of Ca2+ currents is a pharmacological hallmark of SOC channels.

    “The La 3ϩ -induced block of Ca 2ϩ currents is a pharmacological hallmark of SOC channels (3, 4), further strengthening the functional similarity between CMC and SOC channels in mammalian cells.”
  • In eukaryotes, the ER constitutes a finite reservoir of Ca2+ primarily mobilized for signaling that must be replenished to sustain signaling and restore Ca2+ homeostasis.

    “It is known that in eukaryotes the ER constitutes a finite reservoir of Ca 2ϩ primarily mobilized for signaling that must be replenished to sustain the duration of signaling and ultimately restore Ca 2ϩ homeostasis in the ER and the cytosol (1-3, 32).”

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.
