Abstract

Synapses are highly specialized intercellular junctions organized by adhesive and scaffolding molecules that align presynaptic vesicular release with postsynaptic neurotransmitter receptors. The MALS/Veli–CASK–Mint-1 complex of PDZ proteins occurs on both sides of the synapse and has the potential to link transsynaptic adhesion molecules to the cytoskeleton. In this study, we purified the MALS protein complex from brain and found liprin-α as a major component. Liprin proteins organize the presynaptic active zone and regulate neurotransmitter release. Fittingly, mutant mice lacking all three MALS isoforms died perinatally with difficulty breathing and impaired excitatory synaptic transmission. Excitatory postsynaptic currents were dramatically reduced in autaptic cultures from MALS triple knockout mice due to a presynaptic deficit in vesicle cycling. These findings are consistent with a model whereby the MALS–CASK–liprin-α complex recruits components of the synaptic release machinery to adhesive proteins of the active zone.

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

  • CASK binds in vertebrates but not in invertebrates to α-liprins and to CASKIN.

    “CASK additionally binds in vertebrates but not in invertebrates to α-liprins (Olsen et al., 2005; Wei et al., 2011) and to CASKIN (Tabuchi et al., 2002).”

    From The Presynaptic Active Zone (2012) · cites this paper as Olsen et al., 2005

    The Results section confirms that CASK binds liprin-α2, but the Discussion says the liprin-α–CASK interaction is likely conserved in D. melanogaster and C. elegans—the opposite of the claimed vertebrate-only distinction. Olsen et al. is cited for α-liprins in the citing sentence; CASKIN has a separate citation. Page numbers are not provided in our copy. (LLM, conf=0.88)

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.
