Abstract

The transcription factor neuron-restrictive silencer factor/repressor element-1 (RE-1) silencing transcription factor (NRSF/REST) contains nine zinc finger domains and binds to the DNA element, neuron-restrictive silencer element/repressor element-1. REST4, a C-terminally truncated form of NRSF/REST, contains the five N-terminal zinc fingers and binds weakly to DNA yet is transported into the nucleus. To study the contribution of zinc fingers 6-8 to DNA binding, each was mutated. A mutation in zinc finger 6 or 8 had little effect; however, mutation of zinc finger 7 diminished DNA binding. Mutations in any two of these zinc fingers eliminated DNA binding. The contribution of zinc fingers 2-5 to nuclear targeting was studied. Deletion of zinc finger 5 prevented nuclear targeting. Mutations in zinc finger 2, 4, or 5 did not abolish nuclear targeting. However, a zinc finger 3 mutation together with a zinc finger 2 mutation localized to the nuclear envelope. A zinc finger 3 mutation alone or in combination with a zinc finger 4 or 5 mutation produced a punctate nuclear distribution. These results suggest the presence of signals for nuclear targeting, for nuclear entry, and for release from the translocation machinery within zinc fingers 2-5 of REST4.

  • SRRM4 promotes splicing of the REST4 isoform, which has reduced transcriptional repression activity.

    “SRRM4 promotes splicing of the REST4 isoform, which lacks four of the nine zinc fingers found in the full-length protein31 and has reduced transcriptional repression activity32–34.”

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.
