Abstract

The dynamins comprise a large family of mechanoenzymes known to participate in membrane modeling events. All three conventional dynamin genes (Dyn1, Dyn2, Dyn3) are expressed in mammalian brain and produce more than 27 different dynamin proteins as a result of alternative splicing. Past studies have suggested that Dyn1 participates in specialized neuronal functions such as rapid synaptic vesicle recycling, while Dyn2 may mediate the conventional clathrin-mediated uptake of surface receptors. Currently, the distribution, expression, and function of Dyn3 in neurons, or in any other cell type, are completely undefined. Here, we demonstrate that Dyn1 and Dyn3 localize differentially in the synapse. Dyn1 concentrates within the presynaptic compartment, while Dyn3 localizes to dendritic spine tips. Within the postsynaptic density (PSD), we found Dyn3, but not Dyn1, to be part of a biochemically isolated complex comprised of Homer and metabotropic glutamate receptors. Finally, although dominant-negative Dyn3 did not seem to inhibit receptor endocytosis, overexpression of a specific Dyn3 spliced variant in mature neurons caused a marked remodeling of dendritic spines. These data suggest that Dyn3 is a postsynaptic dynamin and, like its binding partner Homer, plays a significant role in dendritic spine morphogenesis and remodeling.

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?

  • Loss of certain cytoskeletal proteins appears to be a common mechanism in AD, PD, and ALS, whereas AD-specific modules are linked to loss of a select group of microtubule and related proteins represented by hubs MAP1B (E-M10) and DNM3 (E-M20).

    “Thus, loss of certain cytoskeletal proteins appears to be a common mechanism in AD, PD, and ALS, whereas AD-specific modules are linked to a loss of a select group of microtubule and related proteins represented respectively by hubs MAP1B (E-M10) and DNM3 (E-M20) (Gray et al., 2003; Kawakami et al., 2003).”

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.
