Abstract

Lenalidomide is a highly effective treatment for myelodysplastic syndrome (MDS) with deletion of chromosome 5q (del(5q)). Here, we demonstrate that lenalidomide induces the ubiquitination of casein kinase 1A1 (CK1α) by the E3 ubiquitin ligase CUL4-RBX1-DDB1-CRBN (known as CRL4(CRBN)), resulting in CK1α degradation. CK1α is encoded by a gene within the common deleted region for del(5q) MDS and haploinsufficient expression sensitizes cells to lenalidomide therapy, providing a mechanistic basis for the therapeutic window of lenalidomide in del(5q) MDS. We found that mouse cells are resistant to lenalidomide but that changing a single amino acid in mouse Crbn to the corresponding human residue enables lenalidomide-dependent degradation of CK1α. We further demonstrate that minor side chain modifications in thalidomide and a novel analogue, CC-122, can modulate the spectrum of substrates targeted by CRL4(CRBN). These findings have implications for the clinical activity of lenalidomide and related compounds, and demonstrate the therapeutic potential of novel modulators of E3 ubiquitin ligases.

  • Proteome-wide mass spectrometry showed selective degradation of endogenous IKZF1/3 and ZFP91 in multiple cell lines.

    “proteome-wide mass-spectrometry demonstrated selective degradation of endogenous IKZF1/3, and ZFP91 in multiple cell lines (3, 4, 16).”

    From Defining the human C2H2 zinc finger degrome targeted by thalidomide analogs through CRBN (2018) · cites this paper as [4]

    The Results section reports global mass-spectrometry profiling in KG-1 cells, and Extended Data Table 1 shows reduced IKZF1 and ZFP91 protein abundance after lenalidomide treatment. Extended Data Figure 8 also describes proteomic measurement of IKZF1 in MDS-L cells. The copy does not show mass-spectrometric degradation of endogenous IKZF3 or establish degradation of all three proteins across multiple cell lines; its IKZF3 assay used a luciferase reporter. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Thalidomide, lenalidomide, and pomalidomide cause ubiquitination and proteasomal degradation of IKZF1 and IKZF3 by bringing a C2H2 zinc finger domain to CRBN, the substrate receptor of CRL4CRBN.

    “The small molecules thalidomide, lenalidomide, and pomalidomide induce the ubiquitination and proteasomal degradation of the transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) by recruiting a Cys2-His2 (C2H2) zinc finger domain to Cereblon (CRBN), the substrate receptor of the CRL4CRBN E3 ubiquitin ligase.”

    From Defining the human C2H2 zinc finger degrome targeted by thalidomide analogs through CRBN (2018) · cites this paper as [4]

    The Discussion and Differential substrate specificity sections (pages not provided) state that all three drugs induce CRL4CRBN-mediated ubiquitination and degradation of IKZF1 and IKZF3. The copy mentions an IKZF1/3 degron but does not identify it as a C2H2 zinc finger domain or explicitly describe the degradation of these proteins as proteasomal. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Thalidomide analogs bind CRBN and change its substrate selectivity so that it recruits, ubiquitinates, and degrades proteins including IKZF1, IKZF3, CK1α, and GSPT1.

    “Thalidomide analogs bind Cereblon (CRBN), the substrate receptor of the CUL4-RBX1-DDB1-CRBN (CRL4CRBN) E3 ubiquitin ligase and alter its substrate selectivity to recruit, ubiquitinate and degrade seemingly unrelated proteins including Ikaros (IKZF1), Aiolos (IKZF3), Casein kinase 1 alpha (CK1α) and GSPT1 (2–7).”

    From Defining the human C2H2 zinc finger degrome targeted by thalidomide analogs through CRBN (2018) · cites this paper as [4]

    The CK1α-substrate and Differential substrate specificity sections (page unavailable) show that CRBN-binding thalidomide analogs can alter substrate selection: the paper reports degradation of IKZF1 and IKZF3 and demonstrates lenalidomide-dependent recruitment, ubiquitination, and degradation of CK1α. It also shows that the analogs differ in which substrates they affect. Our copy does not identify GSPT1 as a substrate (searched: GSPT1 and translation termination factor), so it does not support the full list. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Thalidomide, lenalidomide, and pomalidomide mediate CRL4CRBN-dependent degradation of more proteins than previously appreciated through a C2H2 ZF degron.

    “Thalidomide, lenalidomide and pomalidomide mediate CRL4CRBN-dependent degradation of a larger number of proteins than previously appreciated through a C2H2 ZF degron (3, 4, 16).”

    From Defining the human C2H2 zinc finger degrome targeted by thalidomide analogs through CRBN (2018) · cites this paper as [4]

    The Discussion and Differential substrate specificity sections report CRL4CRBN-mediated degradation of IKZF1 and IKZF3 by all three drugs and identify CK1α as an additional substrate strongly affected by lenalidomide, but not thalidomide. The CK1α is a substrate of CRL4CRBN section says its responsive region has no evident homology to the previously identified IKZF1/3 degron. The paper therefore does not support the claim that the expanded set of proteins is degraded through a C2H2 zinc-finger degron. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • IMiDs can promote degradation of targets lacking a zinc finger domain, including CSNK1A1 and GSPT1.

    “IMiDs can also promote degradation of targets that lack a zinc finger domain, including Casein Kinase 1 alpha (CSNK1A1) (Krönke et al., 2015; Petzold et al., 2016) and GSPT1 (Matyskiela et al., 2016).”

    From Thalidomide promotes degradation of SALL4, a transcription factor implicated in Duane Radial Ray syndrome (2018) · cites this paper as Krönke et al., 2015

    The “Lenalidomide induces degradation of CK1α” section reports that lenalidomide increases ubiquitination and decreases the abundance of CK1α, which is encoded by CSNK1A1. This supports the part of the sentence attributed to Krönke et al.; however, our copy does not explicitly state that CK1α lacks a zinc finger domain. The separate GSPT1 claim is attributed to another citation. (LLM, conf=0.82)

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.
