A Conserved 12-Amino Acid Motif in Sall1 Recruits the Nucleosome Remodeling and Deacetylase Corepressor Complex

Abstract

Sall1 is a multi-zinc finger transcription factor that represses gene expression and regulates organogenesis. In this report, we further characterize the domain of Sall1 necessary for repression. We show that endogenous Sall1 binds to the nucleosome remodeling and deacetylase corepressor complex (NuRD) and confirm the functionality of the Sall1-associating macromolecular complex by showing that the complex possesses HDAC activity. NuRD is involved in global transcriptional repression and regulation of specific developmental processes. The mechanism by which sequence-specific DNA-binding proteins associate with NuRD is not well understood. We have identified a highly conserved 12-amino acid motif in the transcription factor Sall1 that is sufficient for the recruitment of NuRD. Single amino acid substitutions defined the critical amino acid peptide motif as RRKQXK-PXXF. This motif probably exhibits a more general role in regulating gene expression, since other proteins containing this domain, including all Sall family members and an unrelated zinc finger protein Ebfaz, mediate transcriptional repression and associate with NuRD. These results also have important implications for the pathogenesis of Townes-Brocks, a syndrome caused by SALL1 mutations.

  • The extreme N terminus of SALL4 interacts specifically with the NuRD co-repressor complex and can account for transcriptional repression caused by SALL4 recruitment to reporter genes.

    “The extreme N terminus interacts specifically with the nucleosome remodeling and deacetylase (NuRD) co-repressor complex and can account for the transcriptional repression caused by SALL4 recruitment to reporter genes (Lauberth and Rauchman, 2006; Lu et al., 2009).”

  • The N-terminal NuRD binding motif is comparatively depleted of population missense mutations (VdVp = 0.22).

    “Three regions were observed to be comparatively depleted of population missense mutations: the N-terminal NuRD binding motif (Lauberth & Rauchman, 2006) (VdVp = 0.22); a glutamine-rich (Q-rich) sequence that has been reported to participate in SALL protein homo- and heterodimer formation (VdVp = 0.50) (Sweetman et al, 2003); and ZFC4, which is essential for SALL4 function in mice (VdVp = 0.47) (P”

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.
