Developmental function of Elf-1: an essential transcription factor during embryogenesis in Drosophila.
Open accessAbstract
The Drosophila transcription factor Elf-1 binds to a cis-acting element that is essential for neuronal expression of the Dopa decarboxylase gene (Ddc). Elf-1 also stimulates transcription from the Ddc and Ultrabithorax promoters in vitro. To investigate the function of this factor in vivo we have screened for mutations and identified the Elf-1 gene as grainyhead (grh), a previously known embryonic lethal locus. Elf-1/grh mutations cause late embryonic lethality accompanied by multiple defects in the cuticle and head skeleton. Using Ddc-lacZ gene fusions, we show that these mutations affect Ddc expression in the embryo. Surprisingly, however, epidermal expression is disrupted, whereas neuronal expression remains unaffected. Analysis of the mutant phenotype indicates that Elf-1 coordinately regulates multiple genes involved in the differentiation of epidermal structures. The results highlight the importance of genetic analysis in the study of proteins required for developmental regulation of gene expression.

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.
