CYFIP family proteins between autism and intellectual disability: links with Fragile X syndrome

Open access

Abstract

Intellectual disability (ID) and autism spectrum disorders (ASDs) have in common alterations in some brain circuits and brain abnormalities, such as synaptic transmission and dendritic spines morphology. Recent studies have indicated a differential expression for specific categories of genes as a cause for both types of disease, while an increasing number of genes is recognized to produce both disorders. An example is the Fragile X mental retardation gene 1 (FMR1), whose silencing causes the Fragile X syndrome, the most common form of ID and autism, also characterized by physical hallmarks. Fragile X mental retardation protein (FMRP), the protein encoded by FMR1, is an RNA-binding protein with an important role in translational control. Among the interactors of FMRP, CYFIP1/2 (cytoplasmic FMRP interacting protein) proteins are good candidates for ID and autism, on the bases of their genetic implication and functional properties, even if the precise functional significance of the CYFIP/FMRP interaction is not understood yet. CYFIP1 and CYFIP2 represent a link between Rac1, the WAVE (WAS protein family member) complex and FMRP, favoring the cross talk between actin polymerization and translational control.

  • Reduction of Cyfip1 or fly Hspc300 affects the level of the other components of the WRC.

    “Indeed, it is reported that reduction of Cyfip1 or fly Hspc300 affects the level of the other components of the WRC (Kunda et al., 2003; Schenck et al., 2004; Abekhoukh and Bardoni, 2014; Gautier et al., 2011; Qurashi et al., 2007; De Rubeis et al., 2013).”

    From New insights into the regulatory function of CYFIP1 in the context of WAVE- and FMRP-containing complexes (2017) · cites this paper as Abekhoukh and Bardoni, 2014

    The DROSOPHILA section reports that inactivating fly CYFIP reduces expression of the other WAVE-complex members, supporting the CYFIP portion of the claim. The paper identifies HSPC300 as a complex member, but the passages found do not report that reducing fly HSPC300 affects the levels of other members. No page numbers were available in our copy. (LLM, conf=0.85)

  • CYFIP1 interacts with many proteins (Rac, WRC members and membrane components) that are not known partners of FMRP.

    “while it is known that CYFIP1 interacts with many proteins (Rac, WRC members and membrane components) that are not known partners of FMRP (Abekhoukh and Bardoni, 2014).”

    From New insights into the regulatory function of CYFIP1 in the context of WAVE- and FMRP-containing complexes (2017) · cites this paper as Abekhoukh and Bardoni, 2014

    The section “CYFIP PROTEINS: THE WAVE COMPLEX AND BEYOND” (page not provided) describes CYFIP1’s interaction with Rac1, its membership in the WAVE regulatory complex, and a membrane-protein motif that binds a surface formed by CYFIP and Abi2. It distinguishes CYFIP’s WRC role from its interaction with FMRP, but does not state that Rac, WRC members, or those membrane proteins are not known partners of FMRP. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • CYFIP1 and CYFIP2 are members of a protein family that interacts with FMRP in mammals and in the fly.

    “CYFIP1 and CYFIP2 are members of a family of proteins interacting with the Fragile X mental retardation protein (FMRP, encoded by FMR1) in mammals, as well as in the fly (Abekhoukh and Bardoni, 2014; Schenck et al., 2001, 2003).”
  • CYFIP1 and CYFIP2 have been often considered as having the same function.

    “Owing to their high level of homology, CYFIP1 and CYFIP2 have been often considered as having the same function (Abekhoukh and Bardoni, 2014).”
  • FMRP is not only involved in translation regulation and CYFIP1 is a component of complexes that do not contain FMRP.

    “These conclusions are consistent with the fact that FMRP is, indeed, not only involved in translation regulation (Maurin et al., 2014) and CYFIP1 is a component of complexes that do not contain FMRP (Abekhoukh and Bardoni, 2014; Chen et al., 2014).”

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.
