Abstract

The multi-zinc finger proteins of the Sal family regulate organogenesis. Genetic evidence from Drosophila has shown that spalt (sal) can alter gene expression in a cell autonomous fashion, but Sal proteins have never been directly analyzed for their ability to activate or repress transcription. In this report, we show that a member of the Sal family, mouse Sall1, is a potent transcriptional repressor. When fused to a heterologous DNA-binding domain, Sall1 represses transcription of a luciferase reporter by over 100-fold. Expression of the N terminus alone is sufficient for dose-responsive repression that, as shown by deletion analysis, requires the extreme N-terminal amino acids of the protein. The N terminus of Sall1 can repress at both short and long range relative to the promoter, and treatment with the histone deacetylase (HDAC) inhibitor, trichostatin A, alleviates repression by 3-fold. The same regions of the protein that are required for repression physically interact with components of chromatin remodeling complexes, HDAC1, HDAC2, RbAp46/48, MTA-1, and MTA-2. Finally, we demonstrate that Sall1 is localized to discrete nuclear foci and this localization depends on the N-terminal repression domain. Together, these results suggest that the N terminus of mouse Sall1 can recruit HDAC complexes to mediate transcriptional repression.

  • Sall1 and Sall4 both interact biochemically with the NuRD complex.

    “Sall1 and Sall4 have both been shown to interact biochemically with the Nucleosome Remodelling and Deacetylase (NuRD) complex.”

    From Sall4 controls differentiation of pluripotent cells independently of the Nucleosome Remodelling and Deacetylation (NuRD) complex (2016) · cites this paper as Kiefer et al., 2002

    The results (section headed Fig. 2; page unavailable) show biochemical binding of Sall1 to NuRD-associated components MTA1 and MTA2, but report that Mi2 was not detected and describe the complex as likely resembling NuRD. The paper does not report a Sall4 interaction, so it does not support the claim about both proteins. (LLM, conf=0.90)

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.
