Abstract

The E6-AP ubiquitin ligase (human/mouse gene UBE3A/Ube3a) promotes the degradation of p53 in association with papilloma E6 protein, and maternal deficiency causes human Angelman syndrome (AS). Ube3a is imprinted with silencing of the paternal allele in hippocampus and cerebellum in mice. We found that the phenotype of mice with maternal deficiency (m-/p+) for Ube3a resembles human AS with motor dysfunction, inducible seizures, and a context-dependent learning deficit. Long-term potentiation (LTP) was severely impaired in m-/p+ mice despite normal baseline synaptic transmission and neuroanatomy, indicating that ubiquitination may play a role in mammalian LTP and that LTP may be abnormal in AS. The cytoplasmic abundance of p53 was increased in postmitotic neurons in m-/p+ mice and in AS, providing a potential biochemical basis for the phenotype through failure to ubiquitinate and degrade various effectors.

  • Mice with a deletion in the maternal copy of Ube3A have impairments in learning and in the LTP form of synaptic plasticity.

    “Mice that carry a deletion in the maternal copy of Ube3A have impairments in learning and in the LTP form of synaptic plasticity90.”
  • Ube3a protein regulates excitatory-inhibitory balance during brain development, and when its expression is perturbed ASD may occur.

    “These studies suggest that Ube3a protein regulates excitatory–inhibitory balance during brain development and that when the level of expression is perturbed ASD may occur.”
  • In a mouse model with maternal Ube3a deleted (Ube3am−/p+), total brain weight and cortex and cerebellum weights are lower than in wild-type.

    “Similar to the observation of small brain size in human samples from Angelman’s syndrome, the total brain weight, as well as the weight of the cortex and cerebellum, is lower in a mouse model with maternal Ube3a deleted (Ube3am−/p+) [181].”

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.
