Abstract

Holoprosencephaly is a common developmental disorder in humans characterised by incomplete brain hemisphere separation and midface anomalies. The etiology of holoprosencephaly is heterogeneous with environmental and genetic causes, but for a majority of holoprosencephaly cases the genes associated with the pathogenesis could not be identified so far. Here we report the generation of knockout mice for the ubiquitin E3 ligase NOSIP. The loss of NOSIP in mice causes holoprosencephaly and facial anomalies including cleft lip/palate, cyclopia and facial midline clefting. By a mass spectrometry based protein interaction screen we identified NOSIP as a novel interaction partner of protein phosphatase PP2A. NOSIP mediates the monoubiquitination of the PP2A catalytic subunit and the loss of NOSIP results in an increase in PP2A activity in craniofacial tissue in NOSIP knockout mice. We conclude, that NOSIP is a critical modulator of brain and craniofacial development in mice and a candidate gene for holoprosencephaly in humans.

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

  • Loss of NOSIP caused perinatal lethality and holoprosencephaly, a severe impairment in craniofacial development often associated with defective Hedgehog signaling.

    “Loss of NOSIP caused perinatal lethality and holoprosencephaly, a severe impairment in craniofacial development that is often associated with defective Hedgehog signaling.”
  • NOSIP interacts with the C, Aα and B55α subunits, and in vivo loss of NOSIP led to an increase in PP2A activity specifically in palatal and facial tissue.

    “NOSIP interacts with the C, Aα and B55α subunits, and in vivo loss of NOSIP lead to an increase in PP2A activity, specifically in palatal and facial tissue.”
  • NOSIP is a ubiquitin E3 ligase that post-translationally modifies PP2A-C.

    “Another protein that has been shown to post-translationally modify PP2A-C, is nitric oxide synthase interacting protein (NOSIP), a ubiquitin E3 ligase [46].”

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.
