Abstract

The physical distance between presynaptic Ca(2+) channels and the Ca(2+) sensors that trigger exocytosis of neurotransmitter-containing vesicles is a key determinant of the signalling properties of synapses in the nervous system. Recent functional analysis indicates that in some fast central synapses, transmitter release is triggered by a small number of Ca(2+) channels that are coupled to Ca(2+) sensors at the nanometre scale. Molecular analysis suggests that this tight coupling is generated by protein-protein interactions involving Ca(2+) channels, Ca(2+) sensors and various other synaptic proteins. Nanodomain coupling has several functional advantages, as it increases the efficacy, speed and energy efficiency of synaptic transmission.

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

  • The increase in Pr after chemical potentiation might be related to a tightening of the coupling configuration.

    “These results suggest that the increase in Pr after induction of chemical potentiation might be related to a tightening of the coupling configuration [8].”

    From Presynaptic cAMP-PKA-mediated potentiation induces reconfiguration of synaptic vesicle pools and channel-vesicle coupling at hippocampal mossy fiber boutons (2024) · cites this paper as [8]

    In “Specification and regulation of coupling” (page unavailable), the review suggests that channel–sensor coupling may change during presynaptic potentiation. It does not say that potentiation tightens the coupling, or address the cited sentence’s specific chemical-potentiation condition; the reported increase in Pr is the citing authors’ own result. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Biophysical measurements report the coupling distance between Ca2+ channels and release sensors, but the physical correlate of this measure remains undefined.

    “Furthermore, biophysical measurements report the coupling distance between Ca2+ channels and release sensors [7,8] but the physical correlate of this measure remains undefined.”

    From Presynaptic cAMP-PKA-mediated potentiation induces reconfiguration of synaptic vesicle pools and channel-vesicle coupling at hippocampal mossy fiber boutons (2024) · cites this paper as [8]

    The “Tight coupling at fast central synapses” section describes chelator experiments and modelling used to estimate channel–sensor coupling distance. The paper does not say that the physical correlate of that measurement remains undefined; its “From nanodomains to protein complexes” section instead discusses protein–protein interactions as a possible basis for tight coupling. No page numbers are available in our copy. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Ca2+ entry through P/Q-type voltage-gated Ca2+ channels is tightly coupled to the exocytotic release machinery via formation of specialized nanodomains.

    “Ca2+ entry through P/Q channels is tightly coupled to the exocytotic release machinery via formation of specialized “nanodomains” (296).”

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.
