... is the transcription factor Brinker (Brk), yet the expression and potential role of Brk in the germarium has not previously been described. Here, we find that brk expression requires a promoter-proximal element (PPE) to support long-distance enhancer action as well as to drive expression in the germarium. Furthermore...

... pathway in Drosophila , and reduces tissue size. Remarkably, co-expression of Yorkie and miR-8 causes the formation of neoplastic tumors. We show that upregulation of miR-8 represses the growth inhibitor brinker , and depletion of brinker cooperates with Yorkie in the formation of neoplastic tumors. Hence...

... more than one, with Drosophila Brinker (Brk) recruiting the co-repressors CtBP and Groucho (Gro), in addition to possessing a third repression domain, 3R. Previous studies indicated that Gro is sufficient for Brk to repress targets in the wing, questioning why it should need to recruit CtBP, a short...

Much of the regulation of transcriptional output by Dpp is mediated through repression of the transcriptional repressor Brinker (Brk), and thus through the activation of target genes. Mutant cells impaired for Dpp reception or transduction are lost from the wing epithelium...

The Dpp-Brk system converts an inherently uneven growth program, with excessive cell proliferation in lateral regions and low proliferation in medial regions, into a spatially homogeneous profile of cell divisions throughout...

The levels of both Brk and Wg determine which of these PD genes is activated. Surprisingly, Brk does...

... transcription. In the Drosophila wing, expression of genes such as omb and sal along the anteroposterior axis is restricted by lateral-to-medial gradients of the transcriptional repressor Brinker (Brk). omb is less sensitive to repression by Brk than sal and is consequently expressed more laterally. Contrary...

We find that there is a negative correlation between brk activity and growth of the disc:high levels of brk...

HHRE-directed expression is refined along the AP and dorsoventral axes by Brk1, acting through the REPE. In D- h- expressing cells, Dpp signaling is required to block Brk-mediated...
