Drosophila melanogaster pair-rule segmentation gene transcripts localize apically of nuclei in blastoderm embryos. This might occur by asymmetric (vectorial) export from one side of the nucleus or by transport within the cytoplasm. We have followed fluorescently labeled pair-rule transcripts postinjection into Drosophila embryos. Naked, microinjected fushi tarazu (ftz) transcripts do not localize...
In Drosophila, maternal string mRNAs are stable for the first few hours of development, but undergo specific timed degradation at the cellularisation stage. To determine whether the proteins that control this degradation are maternally or zygotically transcribed, we have used in situ hybridisation to determine the fate of maternal string transcripts in mutant embryos which lack individual chromosome...
We have studied the binding of purified TTF-1 on the bovine thyroglobulin gene promoter. DNase I footprinting experiments revealed three binding sites which corresponded in location to the A, B and C sites found in the rat thyroglobulin promoter. Mutants in the A and C regions showing reduced binding of TTF-1, also exhibited largely decreased promoter activity in transient expression experiments in...
