Structure-Based Design of Transcription Factors

Pomerantz, Joel L., Sharp, Phillip A., Pabo, Carl O.·1995·Science

Abstract

Computer modeling suggested that transcription factors with novel sequence specificities could be designed by combining known DNA binding domains. This structure-based strategy was tested by construction of a fusion protein, ZFHD1, that contained zinc fingers 1 and 2 from Zif268, a short polypeptide linker, and the homeodomain from Oct-1. The fusion protein bound optimally to a sequence containing adjacent homeodomain (TAATTA) and zinc finger (NGGGNG) subsites. When fused to an activation domain, ZFHD1 regulated promoter activity in vivo in a sequence-specific manner. Analysis of known protein-DNA complexes suggests that many other DNA binding proteins could be designed in a similar fashion.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Previous studies created chimeric transcription factors recognizing synthetic elements or used phage display to create zinc finger proteins.

    “Previous studies have either created chimeric transcription factors which recognize synthetic regulatory elements by fusing domains from biologically unrelated proteins, or used phage display technology to create a zinc finger protein which recognizes a DNA site generated by a chromosomal translocation”
  • The selectivity of a chimeric transcription factor depends on intermediate affinity and high specificity of isolated subdomains.

    “This is consistent with the overall selectivity of a chimeric transcription factor depending on the intermediate affinity and high specificity of the isolated sub-domains”

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.
