Manual grh loss input
Through DNA affinity chromatography and mass spectrometry, we identified several binding factors many of which are involved in chromatin remodeling.
Competition at the same binding sites results in a cascading effect freeable iso games for psp in which ubiquitous activators regulate genes in a temporally related manner.

Since mutagenesis of the A-box sites within the ind CRM leads to decreased reporter expression and ind endogenous expression is also diminished in grh mutants, this data suggested that Grh drives activation of ind through the A-box; we note however that we cannot dismiss.
A 12 bp sequence was highlighted, as it repeats twice within these 111 bp, and was called the A-box (wttcattcatra).
Lastly, as Dorsal can also function as a repressor, the expression of some genes such as zerknüllt ( zen ) are limited to dorsal regions of the embryo, leading cells in this domain to adopt amnioserosa and non-neurogenic dorsal ectoderm cell fates 2, 6,.Likewise, ectopic expression of dpp in lateralized embryos that exhibit expanded ind expression throughout the embryo was able to repress ind in the domain where Dpp signaling was presented.Previous studies had shown that Grh can function as an activator at later embryonic stages 48,.Zelda and Grh each showed stronger firefox addons status bar affinity for different variations of the shared consensus sequence, but in vitro studies showed they also competed for binding.The Egfr gene is ubiquitously expressed in embryos but the receptor is activated locally in ventrolateral regions by the ligands Vein and Spitz 13,.However, recently it was discovered that the ind gene is expressed in a domain along the DV axis where the Dorsal gradient appears uniform without a clear transition that would be capable of setting a dorsal border.More and more evidence suggests that signaling pathways also help to define gene expression patterns in the early embryo.
