Abstract

Formation of synapses requires specific cellular interactions that organize pre- and postsynaptic compartments. The neuroligin-neurexin complex mediates heterophilic adhesion and can trigger assembly of glutamatergic and GABAergic synapses in cultured hippocampal neurons. Both neuroligins and neurexins are encoded by multiple genes. Alternative splicing generates large numbers of isoforms, which may engage in selective axo-dendritic interactions. We explored whether alternative splicing of the postsynaptic neuroligins modifies their activity toward glutamatergic and GABAergic axons. We find that small extracellular splice insertions restrict the function of neuroligin-1 and -2 to glutamatergic and GABAergic contacts and alter interaction with presynaptic neurexins. The neuroligin isoforms associated with GABAergic contacts bind to neurexin-1alpha and a subset of neurexin-1betas. In turn, these neurexin isoforms induce GABAergic but not glutamatergic postsynaptic differentiation. Our findings suggest that alternative splicing plays a central role in regulating selective extracellular interactions through the neuroligin-neurexin complex at glutamatergic and GABAergic synapses.

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

  • Many known ASD genes, such as neuroligins and neurexins, display complex isoform-specific expression in brain, with different isoforms having distinct functions.

    “Consistent with this notion, many known ASD genes, such as neuroligins and neurexins, display a complex pattern of isoform-specific expression in brain (Boucard et al., 2005; Sudhof, 2008), with different isoforms having very distinct functions (Chih et al., 2006).”

  • NRXNβ AS4- isoforms preferentially bind neuroligin 1 at glutamatergic synapses, whereas NRXNβ AS4+ isoforms preferentially bind NLGN2 at GABAergic and glycinergic synapses.

    “NRXNβ AS4– isoforms preferentially bind neurolignin 1 (B) concentrated at glutamatergic synapses, whereas NRXNβ AS4+ isoforms preferentially bind NLGN2(A) at GABAergic and glycin-ergic synapses93”

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.
